Question

what are micro organisms and the ways of reducing them​

Answer 1

Answer:

They include bacteria, viruses, fungi and microscopic parasites. Micro-organisms are found everywhere (on our bodies, in food, in soil, water and plants). Most micro-organisms are not harmful to humans and many actually colonise and protect us by preventing growth of pathogens.

Microorganisms are controlled by means of physical agents and chemical agents. Physical agents include such methods of control as high or low temperature, desiccation, osmotic pressure, radiation, and filtration.
