Question

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

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

Options

• Both (A) and (R) are true and (R) is the correct explanation of (A)

• Both (A) and (R) are true, but (R) is not the correct explanation of (A)

• (A) is true, but (R) is false

• (A) is false, but (R) is true

Answer 1

Both (A) and (R) are true, but (R) is not the correct explanation of (A)

Explanation:

Decomposition is the conversion of organic material into basic inorganic material. The rate of decomposition changes under the same environmental conditions because detritus composition fluctuates. The decomposition rate is slow if the waste material contains a lot of lignin and cutin.
