Explain the different steps involved in the process of decomposition of detritus. |
|
Answer» The different steps involved in the process of decomposition of detritus are as follows : (i) Fragmentation (ii) Leaching (iii) Catabolism (iv) Humification (v) Mineralization Fragmentation : Breakdown of detritus into smaller particles. e.g., earthworm. Leaching : Water soluble inorganic nutrients go down into the soil horizon and get precipitated as unavailable salts. Catabolism : Bacterial and fungal enzymes degrade detritus into simpler inorganic substances. Humification : It leads to the accumulation of a dark coloured amorphous substance called humus that is highly resistant to microbial action and undergoes decomposition at an extremely slow rate. Mineralisation : The humus is further degraded by some microbes and release inorganic substances by this process. |
