Learner1234:

Help everyone, is an earthworm a decomposer? I found different answers on the Internet. Some sites say yes, some say no. So yes or no?

It is NOT a decomposer. It is a helper of decomposer.

A decomposer breaks down dead organism to SIMPLE substances.

A helper of decomposer breaks down dead organism into SMALLER pieces.

\"How 2 increase the rate of decomposition\"

Yr ans (As 4 as i know) is correct. Adding insects like termites n earthworms the rate of decomposition can b faster.Right ??? Any expert comments?
