Give an example of a bioindicator, and explain why they are important. And write it like a 7 grader

An example of a bioindicator is the presence of lichen on tree bark. Lichen is a type of fungus that grows on trees and rocks. When there is a lot of pollution in the air, lichen can't grow properly. So, if you see a lot of lichen on trees, it means the air is clean. But if there isn't much lichen, it could mean the air is polluted.

Bioindicators are important because they can give us information about the health of an ecosystem. By studying bioindicators, scientists can understand how pollution and other factors are affecting a particular environment. This information can help us make decisions to protect and preserve our environment for the future.
