The correct answer is C.Decomposition.

Explanation:

Decomposition is the process by which dead organisms are broken down by decomposers (such as bacteria, fungi, and scavengers). These decomposers break down the organic matter in the bodies of dead plants and animals, releasing nutrients back into the environment and completing the cycle of matter in ecosystems. During decomposition, carbon is often released as carbon dioxide (CO₂) into the atmosphere, and other nutrients like nitrogen and phosphorus are returned to the soil.

Why the other options are incorrect:

A.Photosynthesis: This is the process by which plants and some microorganisms convert light energy, carbon dioxide (CO₂), and water into glucose (a form of chemical energy) and oxygen. It is the opposite ...
