Discover microorganisms — bacteria, fungi, and other tiny living things — and their important roles in ecosystems.
Microorganisms include bacteria, fungi, and other tiny living things too small to see without a microscope, found almost everywhere on Earth.
Name one type of microorganism.
Bacteria (or fungi)
Why can't we see microorganisms with our naked eyes?
They are far too small — a microscope is needed to magnify them enough to be visible
While some microorganisms cause disease, many are beneficial — helping decompose waste, making foods like yogurt and bread, and supporting ecosystems.
Name one beneficial use of microorganisms.
Making yogurt or bread (fermentation), or decomposing waste materials
Why are decomposer microorganisms important for the environment?
They break down dead organic matter, recycling nutrients back into the soil for other living things to use
