Wetlands play a crucial role in water filtration due to the presence of vegetation, soil, and microorganisms that help remove pollutants, sediments, and excess nutrients from water. This process helps improve water quality and ensures that clean water is available for various ecosystems and human consumption. Wetlands act as natural filters, absorbing and trapping contaminants, thereby preventing them from entering downstream water bodies. This filtration function helps in maintaining the balance of ecosystems and supports biodiversity in aquatic environments.
