[Extra information: 

The garbage containing plant and animal wastes and waste food, when left as such in pits or heaps, is acted upon by bacteria, fungus-like organisms, causing rotting.
Rotting leads to the formation of manure. It is the conversion of complex molecules into simple molecules that can be used by plants for growth and development. Thus, the rotting and conversion of some organic materials into manure is called composting.

Vermicomposting is the method of preparing compost with the help of redworms or earthworms.]
