The process of decomposition is delayed when:

In the carbon cycle,bacteria are essential as:

In the given statements, select the correct option for the process of decomposition.
$(1)$ Moist environment favours decomposition.
$(2)$ Low temperature and anaerobiosis inhibit decomposition.
$(3)$ Decomposition is slower, if detritus is rich in nitrogen.
$(4)$ Decomposition is quicker if detritus is rich in chitin.
$(5)$ Warm environment favours decomposition.

Give scientific reasons: Decomposers are essential in nature.

The topsoil of fertile land appears darker than the soil one meter below. The reason for the color of the topsoil is:

$A$: Detritus food chain begins with detritus.
$R$: Detritivores like fungi and bacteria are major decomposers in such food chains.
