Describe the various steps involved in the process of deconmposition of detritus.

Text Solution

Verified by Experts

Detritus : are raw materials for decomposition
Eg :- Dead plant remains such as leaves, bark, flower and dead animals. Steps in the process of decomposition :
(1) Fragmentation : The process of breaking down detritus into smaller particles. Eg : Earthworm
(2) Leaching : Water soluble inorganic nutrients go down into the soil horizon and get precipitated as unwanted salts.
(3) Cataboism : The process by which bacterial and fungal enzymes degrade detritus into simpler inorganic substances.
(4) Humification : The process that leads to accumulation of a dark coloured amorphous substance called Humus that is highly resistant to microbial action and undergoes decomposition on a extremely slow rate.
(5) Mineralisation : The process by which humus is degraded by microbes and inorganic nutrients are released.
