Microbes have different roles depending on organism and context. Some support normal functions; some can cause illness. A drawing, odor or visible cleanliness cannot identify a pathogen. Use published evidence, not classroom cultures from bodies or surfaces.

Worked example

A claim says every microbe is harmful, so everyone should disinfect their skin constantly. Both the sweeping claim and the proposed action are inappropriate. General hygiene reduces risk without aiming for a sterile body.

Microbes have many roles. Some support normal body functions, some have little effect in a given setting, and some can cause disease. The diagram is conceptual, not a test of any particular microbe or person.

Would you believe it?

Many microbes have helpful roles in and on our bodies. Hygiene reduces harmful spread; it is not a mission to make every body completely microbe-free.
