Autotrophs, by definition, are organisms that are able to internally manufacture their own food. Autotrophs, also known as producers, are organisms that obtain their energy by converting light energy into chemical energy, via photosynthesis. Photosynthesizing plants are an example of autotrophs.
Heterotrophs, by definition, are organisms that are unable to internally manufacture their own food. Heterotrophs, also known as consumers, are organisms that obtain their energy by consuming other organisms. Humans are an example of heterotrophs.
