Other forms: heterotrophs
A heterotroph is an animal that can’t make its own food supply, so they have to eat other things, like plants or other animals, to survive.
People are heterotrophs: we eat plants or meat to stay alive. You might say, well, isn't everything a heterotroph? A lot of creatures are, including giraffes, dogs, fish, horses, and lizards, but plants are not — a plant is an autotroph, because it can feed itself through photosynthesis. There are three types of heterotrophs: are herbivores, carnivores and omnivores. The prefix hetero is a clue to this word’s meaning, since it means other.
