Question

During the process of decomposition in which stage complex organic matter is converted into organic ions and salts by fungi

• A. Mineralisation
• B. Catabolism
• C. Fragmentation
• D. All the above

Answer 1

Answer: (B)

Catabolism

Decomposition is the process of breaking of complex organic matter into simpler inorganic matter. There are five steps of decomposition. These are fragmentation, leaching, catabolism, humification and mineralization. Fragmentation is the process of breaking of detritus into small pieces by detrivores. Leaching is the process of releasing nutrients in the water and seeping into the soil. Catabolism is the process of breaking down of complex organic molecules into the simpler organic ions and salts by fungi. Humification is the process of formation of dark colored humus on the soil. MIneralization is the process of degradation of the hummus to release inorganic nutrients.

Thus, the correct answer is 'Catabolism.'
