Microbes are tiny organisms that usually live in water, soil, and air. As they are very tiny in size, they are not visible to the naked eye so a microscope must be used to see them. They are single-celled organisms like bacteria and fungi that help us to maintain a symbiotic balance within nature.

Microbes keep nature clean by helping break down dead plants and animals into organic matter. Apart from these benefits, they also help with livestock, growth and feed, wastewater treatment, aquaculture, and more.

The human body is home to millions of microbes. Some makes us sick, and some makes us healthy.

The most common and major groups of microorganisms are bacteria, archaea, fungi (yeasts and molds), algae, protozoa, and viruses.
