A)photoautotrophs.

E)chemolithotrophs.

Question

Quizplus · Accepted Answer

Chemoheterotrophs derive their energy from organic compounds (such as glucose) and their carbon from other organic compounds (such as amino acids or fatty acids). This is in contrast to chemoautotrophs, which use inorganic compounds for energy and carbon, and photoautotrophs, which use energy from light to produce organic compounds from inorganic carbon sources. Photoheterotrophs use light energy but still need to take in organic compounds for carbon, and chemolithotrophs use inorganic compounds for both energy and carbon.
