Factors Affecting Decomposition

Q.

Decomposition is aerobic or anaerobic?

Q. Regarding assertion and reason, choose the right option.

Assertion [A]: The rate of decomposition of detritus is reduced in the regions of higher altitude.
Reason: At higher altitudes the temperature becomes very low

1. Both A and R are correct and R explains A

2. Both A and R are correct and R does not explain A
3. Both A and R are incorrect
4. A is correct, R is incorrect

Q. Choose the factor(s) affecting decomposition:

1. Chemical nature of decomposition products.
2. pH of the soil.
3. Temperature of the decomposition site.
4. Consumers living in the decomposition site.

Q. State whether true or false
Detritivores are found in abundance in neutral and slightly alkaline soils.

1. True
2. False

Q. State whether true or false
Decomposers are very active in soils having a temperature of more than ${25}^{\circ }$ C.

1. True
2. False
