Which of the following is not a possible source of energy for chemosynthetic organisms? a. oil b. hydrogen sulfide c. methane d. water

A: Oil

Explanation:

Chemo synthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or methane as a source of energy.

Bacteria living on the sea floor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide.

Chemo synthetic bacteria are organisms that use inorganic molecules as a source of energy and convert them into organic substances. Chemo synthetic bacteria, unlike plants, obtain their energy from the oxidation.

So Oil is not a possible source of energy for Chemo synthesis.
