Microorganisms - Useful Or Harmful

What are Microorganisms?

“Microorganisms are minute organisms that are invisible to the naked eye.”

Microorganisms are so small that they can only be seen under a microscope. These include a huge range of organisms such as bacteria, viruses, fungi, algae, protozoa, etc. These microbes can be beneficial as well as harmful in many ways.

The air we breathe, the food we eat, the water we drink, the floor where we stand, everything around us is inhabited by some or the other type of microorganism. They are even present inside our body.

Few microorganisms can also withstand extreme conditions like a place as hot as boiling water, or a place as cold as ice. Some microorganisms are found alone, while the others are found in colonies. 

Let us have an overview of useful and harmful microorganisms.
