उत्तर
Common detritivores in our ecosystem are earthworms, bacteria and fungi of decay.
Explanation:
Detritivores, such as earthworms, play an important role in breaking down organic materials and recycling nutrients into the soil. This process is critical for maintaining healthy, fertile soil and sustaining plant growth and the ecosystem.

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.
