bioassessment

Bioassessment is the process of evaluating the health of a water body, like a river or lake, by studying the plants, animals, and microorganisms that live there. These living things are good indicators of water quality because they respond to changes in pollution and environmental conditions. By examining their diversity and abundance, scientists can determine if the water is clean, polluted, or changing over time. This approach provides an overall picture of ecosystem health, helping manage and protect water resources effectively.
