Aquatic plants are plants that grow in or near water, such as lakes, rivers, and ponds. They play a vital role in the ecosystem by providing oxygen, food, and habitat for various aquatic animals. Some common types of aquatic plants include water lilies, cattails, and duckweed. These plants can be floating, submerged, or rooted in the soil. These plants also help to improve water quality by filtering pollutants and stabilizing the soil. They can be found in both freshwater and saltwater environments. Aquatic plants are essential for maintaining a balanced ecosystem and supporting biodiversity in aquatic habitats.
