Question

Quizplus · Accepted Answer

Heterotrophs are organisms that cannot synthesize their own organic compounds, and therefore rely on other organisms to obtain these compounds. Autotrophs are the only organisms that can synthesize organic molecules through photosynthesis or chemosynthesis, so heterotrophs must obtain organic molecules from autotrophs.
