NEET BIOLOGY

Detailed explanation-1: -Photoheterotrophs. A heterotroph is an organism that depends on organic matter already produced by other organisms for its nourishment. Photoheterotrophs obtain their energy from sunlight and carbon from organic material and not carbon dioxide.

Detailed explanation-2: -Photoheterotrophs: microbes that use light as a source of energy and organic compounds as the main source of carbon.

Detailed explanation-3: -Organisms that derive their energy from chemosynthesis rather than photosynthesis are called chemoheterotrophs. They extract their energy and carbon from chemical substances. Examples of chemoheterotrophs are fungi and most animals. These organisms use organic chemicals as their energy source.

Detailed explanation-4: -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.
