I want to know more about micro organisms

Microorganisms, or microbes, are tiny living things that are too small to be seen with the naked eye. They include bacteria, archaea, fungi (like yeasts and molds), protists (like amoebas and algae), and viruses. Microbes are found everywhere on Earth, from the deepest oceans to the highest mountains, and play crucial roles in ecosystems, such as decomposition and nutrient cycling.
