During decomposition, the process of mineralization by micro-organisms helps in the release of
Options
- Aorganic nutrients from the humus
- Binorganic nutrients from detritus and formation of humus
- Cboth organic and inorganic nutrients from detritus
- Dinorganic nutrients from humus
Correct answer
D. inorganic nutrients from humus
Step-by-step solution
Mineralization is the last step of decomposition, after humification, during which humus is formed. Humus is colloidal in nature which serves as a reservoir of inorganic nutrients. So, during mineralization inorganic nutrients are withdrawn with the help of microbes. At the level of detritus, fragmentation takes place due to which smaller particles are formed and during catabolism, detritus degrades into smaller inorganic substances with the help of bacterial and fungal enzymes.
