Which step in decomposition involves the degradation of detritus by bacterial and fungal enzymes?

Catabolism

The correct answer is c) Catabolism.

Catabolism is the step in decomposition that involves the degradation of detritus by bacterial and fungal enzymes. During this process, the complex organic matter, such as dead plant remains and animal fecal matter, is broken down into simpler inorganic substances. Bacteria and fungi play a crucial role in the catabolic process by secreting enzymes that break down the detritus into smaller compounds.

These enzymes released by bacteria and fungi target various components of the detritus, such as cellulose, lignin, proteins, and carbohydrates. Through their enzymatic actions, these microorganisms break down the complex organic molecules into simpler forms that can be further utilized by other decomposers or released as inorganic nutrients into the soil.

Catabolism is an important step in the overall process of decomposition as it enables the conversion of complex organic matter into simpler compounds, making them more accessible for further degradation and nutrient cycling within the ecosystem.
