What is a hererotroph?

Answer 1

I think you mean a heterotroph. Heterotrophs are organisms that cannot produce their own food. (basically every organism but plants)

Answer 2

A heterotroph is an organism that cannot produce its own food and relies on consuming other organisms for nutrients. This contrasts with autotrophs, which can make their own food through processes like photosynthesis. Examples of heterotrophs include animals, fungi, and many types of bacteria.
