Answer 1

Sounds like you need someone to do your homework for you. Microbes eat and break down larger molecules into biodegradable. This process helps to dispose of "trash" into molecules we like to think of as healthy like O2, CO2, Nitrogen, etc. By converting these sewage to usable non-harmful materials, we can use them for other purposes like fertilizers, air, etc, thus creating a circle of life.
