प्रश्न
Write the different steps taken in humification and mineralisation during the process of decomposition.

उत्तर
Dead plant remains such as leaves, bark, flowers and dead remains of animals, including fecal matter, constitute detritus, which is the raw material for decomposition. Humification and mineralization occur during decomposition in the soil. Humification leads to accumulation of a dark coloured amorphous substance called humus that is highly resistant to microbial action and undergoes decomposition at an extremely slow rate. Being colloidal in nature it serves as a reservoir of nutrients. The humus is further degraded by some microbes and release of inorganic nutrients occur by the process know as mineralisation.

Observe the contents 1, 2, 3 and 4 of soil samples A, B and C shown in the graph. If the temperature and soil moisture of all soil samples are identical, which soil sample (s) will show faster decomposition?
1 indicates lignin content, 2 indicates chitin, 3 indicates nitrogen content, and 4 indicates sugar content
Identify the correct statements:
- Detrivores perform fragmentation.
- The humus is further degraded by some microbes during mineralization.
- Water soluble inorganic nutrients go down into the soil and get precipitated by a process called leaching.
- The detritus food chain begins with living organisms.
- Earthworms break down detritus into smaller particles by a process called catabolism.
