Question

Quizplus · Accepted Answer

Autotrophs are organisms that can produce their own organic molecules (such as glucose) from inorganic sources of carbon (such as carbon dioxide). In contrast, heterotrophs obtain their organic molecules by consuming other organisms or organic substances derived from other organisms. Therefore, autotrophs and heterotrophs differ in the sources of carbon they use for their metabolism.
