Explain the different steps in the process of decomposition.

Answer»
  • Fragmentation:- 

It is the process of breaking of the detritus into smaller particles by detrivores like earth worm.

  • Leaching:- 

It is the process in which water soluble inorganic substances rundown into soil horizon and get precipitated as salts.

  • Catabolism:- 

The enzymatic conversion of the detritus into simple organic compounds and then into inorganic compounds is called catabolism.
The enzymes are secreted by the decomposers like bacteria and fungal.

  • Humification:- 

Humification during decomposition leads to the accumulation of a dark coloured amorphous substance called, humus.

  • Mineralisation:-

It is the process in which the humus is degraded by certain micro organisms and the inorganic nutrients are released.
