Among the following where do you think the process of decomposition would be the fastest?

1. Tropical rain forest

2. the Antarctic

3. Dry arid region

4. Alpine region

Ans. (a) The lowest strata/store/forest floor of the tropical rain forest recieve little solar radiation and the soil is rich in mineral and humus.

As the high temperature and moisture (humidity) are favorable for the high microbial activity of decomposers to deçompos the fallen leaves and dead organic matter, the process of decomposition is fastest in this type of biome.
