Detailed explanation-1: -Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs.

Detailed explanation-2: -Animals and most of other organisms cannot prepare their own food. They consume food prepared by the plants. So, they are called heterotrophs (heteros = other, trophism = nutrition).

Detailed explanation-3: -Omnivores are heterotrophs that consume both plants and animals. They include pigs, brown bears, gulls, crows, and humans. Omnivores actually fall on a continuum between herbivores and carnivores. Some omnivores eat more plants than animals, whereas other omnivores eat more animals than plants.
