Secondary consumers eat primary consumers. They are carnivores meat-eaters and omnivores animals that eat both animals and plants. Tertiary consumers eat secondary consumers. Quaternary consumers eat tertiary consumers. Food chains "end" with top predators, animals that have little or no natural enemies.

When any organism dies, it is eventually eaten by detrivores like vultures, worms and crabs and broken down by decomposers mostly bacteria and fungi , and the exchange of energy continues. Some organisms' position in the food chain can vary as their diet differs. For example, when a bear eats berries, the bear is functioning as a primary consumer. When a bear eats a plant-eating rodent, the bear is functioning as a secondary consumer.

When the bear eats salmon, the bear is functioning as a tertiary consumer this is because salmon is a secondary consumer, since salmon eat herring that eat zooplankton that eat phytoplankton, that make their own energy from sunlight.

Think about how people's place in the food chain varies - often within a single meal. In any food web, energy is lost each time one organism eats another. Because of this, there have to be many more plants than there are plant-eaters. There are more autotrophs than heterotrophs, and more plant-eaters than meat-eaters. Although there is intense competition between animals, there is also an interdependence.

When one species goes extinct, it can affect an entire chain of other species and have unpredictable consequences. Equilibrium As the number of carnivores in a community increases, they eat more and more of the herbivores, decreasing the herbivore population.

It then becomes harder and harder for the carnivores to find herbivores to eat, and the population of carnivores decreases. In this way, the carnivores and herbivores stay in a relatively stable equilibrium, each limiting the other's population.

A similar equilibrium exists between plants and plant-eaters. Picture Prompt of Fish Eating Fish Write a story about the picture of four fish of decreasing size , chasing each other. Meat is an example of a direct product taken from an animal, which comes from muscle systems or from organs. Food products produced by animals include milk produced by mammary glands , which in many cultures is drunk or processed into dairy products cheese, butter, etc. In addition, birds and other animals lay eggs , which are often eaten, and bees produce honey , a reduced nectar from flowers, which is a popular sweetener in many cultures.

Some cultures consume blood , sometimes in the form of blood sausage , as a thickener for sauces, or in a cured , salted form for times of food scarcity, and others use blood in stews such as jugged hare. Some cultures and people do not consume meat or animal food products for cultural, dietary, health, ethical, or ideological reasons.

Vegetarians choose to forgo food from animal sources to varying degrees. Vegans do not consume any foods that are or contain ingredients from an animal source. Most food has always been obtained through agriculture. With increasing concern over both the methods and products of modern industrial agriculture , there has been a growing trend toward sustainable agricultural practices. This approach, partly fueled by consumer demand, encourages biodiversity , local self-reliance and organic farming methods.

In popular culture, the mass production of food, specifically meats such as chicken and beef , has come under fire from various documentaries , most recently Food, Inc , documenting the mass slaughter and poor treatment of animals, often for easier revenues from large corporations. Along with a current trend towards environmentalism , people in Western culture have had an increasing trend towards the use of herbal supplements , foods for a specific group of people such as dieters, women, or athletes , functional foods fortified foods, such as omega-3 eggs , and a more ethnically diverse diet.

Several organisations have begun calling for a new kind of agriculture in which agroecosystems provide food but also support vital ecosystem services so that soil fertility and biodiversity are maintained rather than compromised.

According to the International Water Management Institute and UNEP , well-managed agroecosystems not only provide food, fiber and animal products, they also provide services such as flood mitigation , groundwater recharge , erosion control and habitats for plants, birds, fish and other animals. Animals, specifically humans, have five different types of tastes: As animals have evolved , the tastes that provide the most energy sugar and fats are the most pleasant to eat while others, such as bitter , are not enjoyable.

Generally regarded as the most pleasant taste, sweetness is almost always caused by a type of simple sugar such as glucose or fructose , or disaccharides such as sucrose , a molecule combining glucose and fructose. Artificial sweeteners such as sucralose are used to mimic the sugar molecule, creating the sensation of sweet, without the calories. Other types of sugar include raw sugar , which is known for its amber color, as it is unprocessed. As sugar is vital for energy and survival, the taste of sugar is pleasant.

The stevia plant contains a compound known as steviol which, when extracted, has times the sweetness of sugar while having minimal impact on blood sugar. Sourness is caused by the taste of acids , such as vinegar in alcoholic beverages.

Sour foods include citrus , specifically lemons , limes , and to a lesser degree oranges. Sour is evolutionarily significant as it is a sign for a food that may have gone rancid due to bacteria. Saltiness is the taste of alkali metal ions such as sodium and potassium. It is found in almost every food in low to moderate proportions to enhance flavor, although to eat pure salt is regarded as highly unpleasant. There are many different types of salt, with each having a different degree of saltiness, including sea salt , fleur de sel , kosher salt , mined salt, and grey salt.

Other than enhancing flavor, its significance is that the body needs and maintains a delicate electrolyte balance, which is the kidney 's function. Salt may be iodized, meaning iodine has been added to it, a necessary nutrient that promotes thyroid function.

Some canned foods, notably soups or packaged broths , tend to be high in salt as a means of preserving the food longer. Historically salt has long been used as a meat preservative as salt promotes water excretion.

Similarly, dried foods also promote food safety. Bitterness is a sensation often considered unpleasant characterized by having a sharp, pungent taste. Unsweetened dark chocolate , caffeine , lemon rind, and some types of fruit are known to be bitter.

Umami , the Japanese word for delicious, is the least known in Western popular culture but has a long tradition in Asian cuisine. Umami is the taste of glutamates , especially monosodium glutamate MSG. Many scholars claim that the rhetorical function of food is to represent the culture of a country, and that it can be used as a form of communication.

According to Goode, Curtis and Theophano, food "is the last aspect of an ethnic culture to be lost". Many cultures have a recognizable cuisine, a specific set of cooking traditions using various spices or a combination of flavors unique to that culture, which evolves over time. Other differences include preferences hot or cold, spicy, etc. Many cultures have diversified their foods by means of preparation, cooking methods, and manufacturing.

This also includes a complex food trade which helps the cultures to economically survive by way of food, not just by consumption.

Various cultures throughout the world study the dietary analysis of food habits. While evolutionarily speaking, as opposed to culturally, humans are omnivores , religion and social constructs such as morality , activism , or environmentalism will often affect which foods they will consume. Food is eaten and typically enjoyed through the sense of taste , the perception of flavor from eating and drinking.

Certain tastes are more enjoyable than others, for evolutionary purposes. Aesthetically pleasing and eye-appealing food presentations can encourage people to consume foods.

A common saying is that people "eat with their eyes". Food presented in a clean and appetizing way will encourage a good flavor, even if unsatisfactory.

Texture plays a crucial role in the enjoyment of eating foods. Contrasts in textures, such as something crunchy in an otherwise smooth dish, may increase the appeal of eating it. Common examples include adding granola to yogurt , adding croutons to a salad or soup , and toasting bread to enhance its crunchiness for a smooth topping, such as jam or butter. Another universal phenomenon regarding food is the appeal of contrast in taste and presentation. For example, such opposite flavors as sweetness and saltiness tend to go well together, as in kettle corn and nuts.

While many foods can be eaten raw, many also undergo some form of preparation for reasons of safety, palatability , texture , or flavor. At the simplest level this may involve washing, cutting, trimming, or adding other foods or ingredients, such as spices. It may also involve mixing, heating or cooling, pressure cooking , fermentation, or combination with other food. In a home, most food preparation takes place in a kitchen. Some preparation is done to enhance the taste or aesthetic appeal; other preparation may help to preserve the food; others may be involved in cultural identity.

A meal is made up of food which is prepared to be eaten at a specific time and place. The preparation of animal-based food usually involves slaughter , evisceration , hanging, portioning, and rendering. In developed countries, this is usually done outside the home in slaughterhouses , which are used to process animals en masse for meat production.

Many countries regulate their slaughterhouses by law. For example, the United States has established the Humane Slaughter Act of , which requires that an animal be stunned before killing. Strict interpretations of kashrut require the animal to be fully aware when its carotid artery is cut.

On the local level, a butcher may commonly break down larger animal meat into smaller manageable cuts, and pre-wrap them for commercial sale or wrap them to order in butcher paper. In addition, fish and seafood may be fabricated into smaller cuts by a fish monger. However, fish butchery may be done on board a fishing vessel and quick-frozen for preservation of quality.

The term "cooking" encompasses a vast range of methods, tools, and combinations of ingredients to improve the flavor or digestibility of food. Cooking technique, known as culinary art , generally requires the selection, measurement, and combining of ingredients in an ordered procedure in an effort to achieve the desired result.

Constraints on success include the variability of ingredients, ambient conditions, tools , and the skill of the individual cook. Cooking requires applying heat to a food which usually, though not always, chemically changes the molecules, thus changing its flavor, texture , appearance, and nutritional properties.

There is archaeological evidence of roasted foodstuffs at Homo erectus campsites dating from , years ago. Different cuisines will use different types of ovens. For example, Indian culture uses a tandoor oven, which is a cylindrical clay oven which operates at a single high temperature. Classic Italian cuisine includes the use of a brick oven containing burning wood. Ovens may be wood-fired, coal-fired, gas , electric, or oil-fired. Various types of cook-tops are used as well.

They carry the same variations of fuel types as the ovens mentioned above. Cook-tops are used to heat vessels placed on top of the heat source, such as a sauté pan , sauce pot, frying pan , or pressure cooker. These pieces of equipment can use either a moist or dry cooking method and include methods such as steaming , simmering , boiling , and poaching for moist methods, while the dry methods include sautéing , pan frying , and deep-frying.

In addition, many cultures use grills for cooking. A grill operates with a radiant heat source from below, usually covered with a metal grid and sometimes a cover. An open pit barbecue in the American south is one example along with the American style outdoor grill fueled by wood, liquid propane, or charcoal along with soaked wood chips for smoking.

In Argentina , an asado Spanish for "grilled" is prepared on a grill held over an open pit or fire made upon the ground, on which a whole animal or smaller cuts are grilled. Certain cultures highlight animal and vegetable foods in a raw state.

Salads consisting of raw vegetables or fruits are common in many cuisines. Sashimi in Japanese cuisine consists of raw sliced fish or other meat, and sushi often incorporates raw fish or seafood.

Steak tartare and salmon tartare are dishes made from diced or ground raw beef or salmon, mixed with various ingredients and served with baguettes , brioche , or frites. Restaurants employ trained chefs who prepare food, and trained waitstaff to serve the customers. The term restaurant is credited to the French from the 19th century, as it relates to the restorative nature of the bouillons that were once served in them. However, the concept pre-dates the naming of these establishments, as evidence suggests commercial food preparation may have existed during the age of the city of Pompeii , and urban sales of prepared foods may have existed in China during the Song dynasty.

The coffee shops or cafés of 17th century Europe may also be considered an early version of the restaurant.

Expenditures by type of out-of-home dining were as follows: Packaged foods are manufactured outside the home for purchase. This can be as simple as a butcher preparing meat, or as complex as a modern international food industry. Early food processing techniques were limited by available food preservation, packaging, and transportation. This mainly involved salting , curing , curdling, drying , pickling , fermenting , and smoking.

It brought the advantages of pre-prepared time-saving food to the bulk of ordinary people who did not employ domestic servants. At the start of the 21st century, a two-tier structure has arisen, with a few international food processing giants controlling a wide range of well-known food brands. There also exists a wide array of small local or national food processing companies.

Computer-based control systems, sophisticated processing and packaging methods, and logistics and distribution advances can enhance product quality, improve food safety , and reduce costs.

Britain 's need for food was especially well illustrated in World War II. Despite the implementation of food rationing , Britain remained dependent on food imports and the result was a long term engagement in the Battle of the Atlantic. Food is traded and marketed on a global basis. The variety and availability of food is no longer restricted by the diversity of locally grown food or the limitations of the local growing season. In , over countries became signatories to the Uruguay Round of the General Agreement on Tariffs and Trade in a dramatic increase in trade liberalization.

This included an agreement to reduce subsidies paid to farmers, underpinned by the WTO enforcement of agricultural subsidy , tariffs , import quotas , and settlement of trade disputes that cannot be bilaterally resolved. Trade liberalization has greatly affected world food trade.

Food marketing brings together the producer and the consumer. Ha bollito il corpo con degli ortaggi per fare un delizioso brodo di pollo. Breeding the common stock with purebreds improves the quality of the herd. The company issues two classes of equity: Per una buona bouillabaisse, la prima cosa da fare è preparare il brodo di pesce.
