Autotrophs and heterotrophs differ in the mode in which they USE DIFFERENT sources of carbon.

Autotrophs are organisms that synthesize their own food, thereby they obtain carbon from inorganic sources.

Examples of autotrophic organisms include plants and algae.

Heterotrophs are organisms that cannot synthesize their own food, thereby they need to obtain carbon from other organisms.

Examples of heterotrophic organisms include animals and fungi.

In conclusion, autotrophs and heterotrophs differ in the mode in which they USE DIFFERENT sources of carbon.
