Floating and oxygen plants

Floating and oxygen plants

Aquatic plants are very important in a pond. They are not only beautiful to look at, but also play an important role in the biological balance of the pond. During their growth, aquatic plants absorb nutrients from the pond water. This keeps the pond clear. This is especially true for the oxygenating plants. These plants grow completely under water. Source: Wikipedia
