Autotrophs and heterotrophs differ in that the latter depends on external sources for their foods while the former has the capacity to synthesize their own foods.
Autotrophs are living organisms that have the capacity to synthesize their own foods. They are able to do so by a process known as photosynthesis.
Autotrophs have the capacity to use radiant energy from the sun to manufacture carbohydrates because they possess a green molecule known as chlorophyll.
Heterotrophs, on the other hand, have no capacity to synthesize their foods. Thus, they depend on external sources. They can be herbivorous, carnivorous, or omnivorous that feed on plant only, meat only, or both plant and meat respectively.
