Quizplus · Accepted Answer

Autotrophs are organisms that can use carbon dioxide as their sole or principal source of carbon. They are able to do this through the process of photosynthesis or chemosynthesis, which allows them to produce their own organic compounds without relying on other organisms for a source of carbon. Auxotrophs, prototrophs, and heterotrophs all require an external source of organic carbon to survive.
