What place do microorganisms occupy in living nature?

Microscopic organisms are tiny life forms, often made up of a single cell and highly sensitive to change.

They are vital in the food chain and for the health of our planet. They are the backbone of the marine food web and, directly or indirectly, are food for everything else on the high seas.

In addition, these microscopic organisms play a role in maintaining the Earth’s atmosphere – they help remove carbon dioxide and release chemicals that help form clouds. Scientists are studying microscopic organisms in Antarctica to better understand atmospheric changes and ozone depletion.
