microscopic organisms
Tiny living things
Microscopic organisms are living things too small to see without magnification—bacteria, viruses, protozoa, some fungi and algae.
The phrase appears in scientific contexts and everyday speech about germs, disease, or the invisible life teeming in water, soil, and our bodies: Microscopic organisms in the gut aid digestion.
Often shortened to microorganisms or microbes.
