In the animal world there are different food chains. There are species that use exclusively plant-based diet, they are herbivores. For example, the usual diet of the jackrabbit is juicy grass, shoots of plants and the bark of trees. Bees feed on pollen and nectar from the flowers.
Predatory animals, which include wolves, tigers, lions, owls, and even ladybugs in the process of hunting for live prey get their food. Food for predators can serve large mammals, rodents, and various small animals, bird eggs, carrion.
Is in the nature and these animals that eat plant food along with other meats. Why they are called omnivores.
