Which Prokaryotic Nutritional Group Use Organic Substances for Carbon and Photons

Question

Which prokaryotic nutritional group use organic substances for carbon and photons for energy?  
A) Photoautotrophs
B) Chemoautotrophs
C) Photoheterotrophs
D) Chemoheterotrophs
E) Methanoheterotrophs

Accepted Answer

Photoheterotrophs are prokaryotic organisms that use organic substances for carbon and photons for energy. They are different from photoautotrophs, which use light for both carbon and energy, and chemoautotrophs, which use inorganic substances for energy and carbon. Chemoheterotrophs use organic substances for both energy and carbon, while methanoheterotrophs use methane as a source of energy and organic substances for carbon.
