Aquatic flora is a term used to describe the plants that live in water, such as ALGAE. ALGAE is the most common type of aquatic flora, and it is an important part of the food chain in many aquatic ecosystems. ALGAE can range from single-celled organisms to complex multicellular forms, and they are found in both freshwater and saltwater environments. Aquatic flora also includes other types of plants, such as seaweeds, mosses, and ferns. These plants provide food and shelter for many aquatic animals, and they also help to maintain the balance of oxygen and carbon dioxide in the water.
