Which is a characteristic of a virus, but not a bacterium?

Bacteria are single-celled, prokaryotic microorganisms. They can be either "good" or "bad" for the health of plants, humans, and other animals that come into contact with them. A virus is acellular (has no cell structure) and requires a living host to survive. and causes illness in its host.

Iwould say overuse ( but not 100% sure ) in the u.s. we tend to overuse water by leaving it running, throwing it away, taking long showers, etc.
