C)other organic compounds
D)light
E)heat

Question

Quizplus · Accepted Answer

Photoautotrophs use light as their source of energy for the synthesis of organic molecules. Carbon dioxide serves as the primary source of carbon, but it is not the source of energy. Inorganic compounds and other organic compounds may serve as sources of nutrients or building blocks for the synthesis of organic molecules, but they are not the source of energy. Heat is not a direct source of energy for the synthesis of organic molecules in photoautotrophs.
