What are the benefits of the anarcharis pond plant?

It is often called the waterweeds. The American water weed lives entirely underwater with the exception of small white flowers which bloom at the surface and are attached to the plant by delicate stalks. Silty sediments and water rich in nutrients favor the growth of American water weed in nutrient-rich lakes. However, the plant will grow in a wide range of conditions. It is found throughout temperate North America, where it is one of the most common aquatic plants. American water weed is an important part of lake ecosystems. It provides good habitat for many aquatic invertebrates and cover for young fish and amphibians. Waterfowl, especially ducks, as well as beaver and muskrat eat this plant. Also, it is of economic importance as an attractive and easy to keep aquarium plant.
