[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.

A landfill is an area where a lot of garbage is collected, spread out, and covered with soil.

Recycling is a process in which materials are reused in the same or another form.]
