<P> Omnivore / ˈɒmnivɔːr / is a consumption classification for animals that have the capability to obtain chemical energy and nutrients from materials originating from plant and animal origin . Often, omnivores also have the ability to incorporate food sources such as algae, fungi, and bacteria into their diet as well . </P> <P> Omnivores come from diverse backgrounds that often independently evolved sophisticated consumption capabilities . For instance, dogs evolved from primarily carnivorous organisms (Carnivora) while pigs evolved from primarily herbivorous organisms (Artiodactyla). What this means is that physical characteristics are often not reliable indicators of whether an animal has the ability to obtain energy and nutrients from both plant and animal matter . Owing to the wide range of entirely unrelated organisms independently evolving the capability to obtain energy and nutrients from both plant and animal materials, no generalizations about the anatomical features of all omnivores can realistically be made . </P>

An animal that eat both plants and animals
