Final answer:
Heterotrophs are organisms that rely on other living things for food. Unlike autotrophs, they cannot produce their own food through photosynthesis. Examples of heterotrophs include animals, fungi, and some bacteria.

They are unable to produce their own food through photosynthesis, unlike autotrophs which can convert sunlight into energy. Heterotrophs obtain nutrients by consuming other organisms or organic matter. Examples of heterotrophs include animals, fungi, and some bacteria.
