Microorganism

Definition - What does Microorganism mean?

A microorganism is any living organism like bacteria, protozoa, or even fungi that cannot be seen with the naked eye. Microorganisms can only be viewed through a microscope and are extremely important to plant life, plant health, and soil composition.

MaximumYield explains Microorganism

No plant or animal could live without the beneficial microorganisms at work in nature.

Microorganisms are the billions of tiny living creatures that eat fallen leaves, bark, or trees. They also are the cause of the process of decomposition. There are also microorganisms that prey on harmful insects or bacteria that may infect a plant.

Yeast is also an example of a beneficial microorganism.

The byproduct of many microorganisms and the decomposition is the castings or dung that remains from the process. This is where soils and composts derive their nutritious nature from.

But some microorganisms, particularly bacteria, are parasitic and can have a negative effect on plants, animals, or humans by attacking the very cells that comprise a more complex living organism. They prey and feed on other beneficial bacteria and microorganisms in the form of a disease that the body or plant must fight off through their immune system.
