Question

how do micro organisms keep the environment clean

Answer 1

To help clean up the disaster, scientists used microorganisms that converted the hazardous oil into less toxic compounds. This natural process, called biodegradation, happens when microbes like bacteria and fungi break down complex pollutants into simpler substances to gain energy and nutrients

Answer 2

Micro organisms eats up the dead bodies of animals and convert it into humus. They also eats up biodegradable waste. Some types of microorganisms can also eat plastics. In this way they keep the environment clean.
