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.

The rate of decomposition of detritus is affected by the abiotic factors like availability of oxygen, pH of the soil substratum, temperature etc. Discuss.


Assertion (A): Decomposition process is slower if detritus is rich in lignin and cutin.

Reason (R): Decomposition is largely an oxygen requiring process.
