Final answer:

Microorganisms are tiny living organisms that require a microscope to be seen, with viruses being even smaller than bacteria.


Explanation:

Microorganisms are generally too small to be seen without a microscope. For example, bacterial cells are typically about 1 µm in size, making them smaller than animal cells which are around 10 µm across.

Some microorganisms, like viruses, can be even smaller than bacteria. These microbes differ not only in size but also in structure, habitat, and metabolism.
