Give an example of a bioindicator, and explain why they are important

Answer 1

One example of a bioindicator is the presence of lichens on trees and rocks. Lichens are a symbiotic organism made up of a fungus and algae that are extremely sensitive to air pollution and changes in the environment. If lichens are absent or in poor condition, it may indicate high levels of air pollution in the area.

Bioindicators are important because they provide valuable information about the health of an ecosystem and can help identify environmental issues before they become more severe. By monitoring bioindicators, scientists and researchers can track changes in the environment and take action to protect and preserve ecosystems. Additionally, bioindicators can also be used to assess the effectiveness of conservation efforts and environmental policies.
