Summary
Fungi and bacteria are microorganisms that can only be seen under a microscope. Both can be useful or harmful, and they play a role as decomposers by feeding on dead matter.

- Bacteria — microorganisms that cannot be seen with the naked eye and are decomposers. Example: Some bacteria are used in making yogurt.
- Decomposer — an organism that feeds on dead matter. Example: Fungi and bacteria are decomposers.
