Microorganisms

Microorganisms are small living organisms that cannot be seen with the naked eye, such as bacteria, viruses, fungi, and protozoa.

Microorganisms play a crucial role in the environment by decomposing organic matter, cycling nutrients, and contributing to the ecosystem's balance.

Some examples of beneficial microorganisms include those used in food production (such as yeast in bread-making), those involved in nitrogen fixation (such as bacteria in legume root nodules), and those used in the production of antibiotics.
