tiny living entity visible only under a microscope
A microorganism, also known as a microbe, is a tiny living organism that can only be seen with a microscope. These include bacteria, viruses, fungi, and protozoa. Microorganisms play crucial roles in various biological processes, such as decomposition, fermentation, and even human health, where they can be both beneficial (like gut bacteria) and harmful (like pathogens causing diseases).
