Give me the best example about germs ! i need it for science.

A germ is a microorganism that may cause diseases.

There are four types of germ.

1) bacteria - single celled creatures that are present everywhere.Good bacteria help in food digestion. Bad bacteria cause sickness and infection.

2) viruses - must live in a living host to survive. they reproduce and spread throughout the body of the host and cause sickness like chickenpox, flue, and measles, to name a few.

3) fungi - multi-celled plant-like organism that live in damp, warm places. Athelete's foot is caused by fungi.

4) protozoa - one-cell organism that loves moist places and often spread diseases through water. Some protozoa cause intestinal infection manifested by diarrhea, nausea, and belly pain.

Gasses as an state of matter are far apart and spread out.
