What is the importance of aquatic plants in controlling water quality?

Aquatic plants play a crucial role in maintaining and improving water quality through their ability to absorb excess nutrients, such as nitrogen and phosphorus, which can lead to harmful algal blooms if present in high concentrations. By taking up these nutrients from the water, aquatic plants help to prevent nutrient pollution and contribute to a balanced ecosystem. Additionally, they filter pollutants, which can enhance water clarity and overall health of aquatic environments.

The presence of aquatic plants supports the habitat for numerous aquatic organisms, enriching biodiversity. They also provide oxygen through photosynthesis, which is vital for the survival of fish and other aquatic life. Overall, their functions establish a natural filtration system that promotes cleaner and healthier waterways.
