What kind of animals help clean water?

Answer 1

Certain species of animals play vital roles in cleaning water ecosystems. For instance, filter-feeding animals like mussels and clams can improve water quality by filtering out pollutants and particulates. Aquatic plants, while not animals, also contribute by absorbing excess nutrients and providing habitat for fish and other wildlife, further enhancing water clarity. Additionally, some fish species help control algae populations, which can otherwise lead to water degradation.
