Question

Microorganisms are called 'environment cleaners.' explain

Answer 1

Microorganisms are environmental cleaners largely because they carry out the function of decomposition in the environment. Saprophytic microorganisms, such as some types of bacteria and fungi, are responsible for the breakdown of the dead organic matter. This is the process of decomposition where the complex organic matter of dead organisms are broken down to simpler organic compounds which are recyclable into the ecosystem.
