Question

What do you call bacteria that use organic molecules both for energy and carbon source?

• A. Photoautotrophs
• B. Photoheterotrophs
• C. Chemoautotrophs
• D. Chemoheterotrophs

Answer 1

The correct option is D Chemoheterotrophs

Chemoheterotrophs get their energy and carbon from organic compounds.

Photoautotrophs are the organisms that use the sun as the source of energy and carbon dioxide, an inorganic compound as source of carbon.

Photoheterotrophs are the organisms that use the sun as the source of energy, and organic compounds as sources of carbon.

Chemoautotrophs are organisms that obtain energy from oxidation of inorganic substances and carbon from inorganic compounds such as carbon dioxide.
