All animals on the degree of specialization of the feed divided into two types - stenofagov (eat one food or feed similar in composition) and eurifagov (omnivores).
Pantophagy means the ability of animals to use in writing the widest range of products and organisms: plants, fungi, and other animals.
omnivores (eurifagi) live mainly in cold and temperate zones of the northern hemisphere.Harsh conditions forced nature of these animals in the course of evolution to change their type of power so as to adapt to survive in cold conditions, the seasons and the frequency of occurrence of certain food groups.In the summer, they had to eat the plants in the winter to hunt other animals.As a result, they have become accustomed to the change of diet, choosing the most suitable food for themselves, depending on forces them to this fact.These animals are very much much more than you might expect.
This group includes quite dissimilar animals.These include, for example, brown bear, pig, hedgehog, badger, raccoon dog, squirrel, wild boar, gray rat, mouse, rat, hoodie, and many others.All of them are characterized by a mixed type of food and, therefore, called the term "omnivores".Examples can be continued.
addition to the above, this group includes some species of primates, including chimpanzees.Various bird rides berries and nectar, along with insects, worms, fish and small rodents (chickens, crows and others).Certain types of lizards, turtles, fish (piranha) and omnivores.Some species are able to eat even omnivorous scavengers.
Create for a given combination of "omnivore" list is quite difficult, because a lot of them and they are able to change the type of food.For example, chimpanzees, whose DNA is 99% the same as ours, feed mainly on fruits, seeds and nuts, animal food in their diet is only 5%.However, there are cases where they are hunted not only for ants, birds and some small mammals, but even in other primates (baboons, monkeys, prosimians galago, colobus monkeys, potoo).
All organisms that belong to the type of food to one group belong to the same trophic level (first, second, etc.).Omnivores are animals to several trophic levels, their participation in each is determined by the composition of their diet.
terms "carnivorous" and "herbivorous" (zoophages and herbivores) are often quite conditional upon closer study of many species of animals.Most carnivores sometimes eat fruits and herbivorous - insects and bird eggs.
Many eurifagi (bear, badger, wild boar, marten, fox, and others) are able to periodically change the group of the consumed food.This forced adaptation to life in conditions of unstable food supply.
omnivores and consume plant and animal food.From this perspective, the man on the biological definition, also belongs to this group.This fully confirms its anatomy and physiology.Man successfully can even eat raw meat, quite happily digesting it (examples: the peoples of the North eat raw fish and meat fresh, frozen and dried form, the Japanese also eat raw fish and raw seafood; Italians traditionally love to eat carpaccio, etc.)
omnivore possess intermediate-minded, they are quite cautious and calm, like herbivores, and at the same time able to be active in the search for prey like carnivores (meat-eating).They are able to remember them useful information about the environment and reproduce it if necessary, know how to get food or find a safe shelter.
judge about what the animal eats mostly can be on the specifics of the structure of his jaws.
