EVERYDAY SCIENCE

Detailed explanation-1: -Answer and Explanation: (C.) Chemoheterotrophs are bacteria that must consume organic molecules to obtain both energy and carbon. Chemoheterotrophs cannot perform photosynthesis, so they are dependent on other organic substances for energy.

Detailed explanation-2: -Chemoheterotrophs: microbes that use organic chemical substances as sources of energy and organic compounds as the main source of carbon.

Detailed explanation-3: -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-4: -So, the correct option is ‘chemoheterotrophs’.

Detailed explanation-5: -Heterotrophic bacteria, which include all pathogens, obtain energy from oxidation of organic compounds. Carbohydrates (particularly glucose), lipids, and protein are the most commonly oxidized compounds. Biologic oxidation of these organic compounds by bacteria results in synthesis of ATP as the chemical energy source.
