Detailed explanation-1: -Photoheterotrophs: microbes that use light as a source of energy and organic compounds as the main source of carbon.

Detailed explanation-2: -Autotrophic organisms (chemosynthetic and photosynthetic bacteria, algae, and plants) derive this essential element from carbon dioxide. Heterotrophs use preformed organic compounds as their source of carbon.

Detailed explanation-3: -Examples of photoheterotrophic organisms include purple non-sulfur bacteria, green non-sulfur bacteria, and heliobacteria. Recent research has indicated that the oriental hornet and some aphids may be able to use light to supplement their energy supply.

Detailed explanation-4: -Chemoheterotrophs: microbes that use organic chemical substances as sources of energy and organic compounds as the main source of carbon.

Detailed explanation-5: -Chemoautotrophs are organisms that obtain energy from oxidation of inorganic substances and carbon from inorganic compounds such as carbon dioxide.
