Heterotrophs are regarded as consumers that obtain carbon by means of eating other heterotrophs or autotrophs, rather than obtaining it from energy of light or inorganic oxidation. Basically, all animals are heterotrophs. In order for a particular species to be heterotroph, it has to obtain carbon from any member of an organic compound class, the molecules of which contain carbon. A bear is a representative of omnivores. It consumes both heterotrophs and autotrophs. Belongs to Mammalia class, Ursidae family. General features: a stocky mammal of medium to large size with black, brown, reddish, or white fur; mostly inhabit forests, tundra, deserts, swamps, and rain forests; are generally distributed in Northern Hemisphere. Certain species have distinct lines on throat, chest, and face. Bears have considerably large heads, short tails, small forward-facing eyes, and modestly sized ears. Their diet depends on geographical location and may vary from species to species. Most of the bears, however, feed on whatever they find. For instance, the polar bears feed primary on seals, but may it berries and shrubbery as well.  The panda bears, on the other hand, are primarily herbivores, eating plants, shoots, and bamboo leaves.
