Question

The important step(s) in the process of decomposition is/are ____________________.

• A. Fragmentation
• B. Leaching and catabolism
• C. Huminification and mineralization
• D. All of the above

Answer 1

The correct option is D

All of the above

A number of processes are involved in decomposition. They are grouped into three categories, i.e., fragmentation of detritus, leaching and catabolism. Decomposition leads to the formation of two products, humus and inorganic nutrients (minerals). Processes involved in their formation are called humification and mineralisation respectively. Thus all these steps i.e fragmentation, leaching, catabolism, humification and mineralisation are important for the complete decomposition of detritus into simpler compounds and inorganic substances.
