NEET BIOLOGY

Detailed explanation-1: -Chemoheterotrophs: microbes that use organic chemical substances as sources of energy and organic compounds as the main source of carbon.

Detailed explanation-2: -Chemoheterotrophs are organisms that get their energy source and carbon source from organic sources. Chemoheterotrophs must consume organic building blocks that they are unable to make themselves. Most get their energy from organic molecules such as sugars.

Detailed explanation-3: -Chemoheterotrophs are bacteria that must consume organic molecules to obtain both energy and carbon.

Detailed explanation-4: -So, the correct option is ‘chemoheterotrophs’.

Detailed explanation-5: -Chemoautotrophs can use inorganic energy sources such as hydrogen sulfide, elemental sulfur, ferrous iron, molecular hydrogen, and ammonia or organic sources to produce energy.
