What role do phytoplankton play in an aquatic environment?


Wiki User

Q.What is the role of phytoplankton in an aquatic ecosystem?

Ans.Phytoplankton are microscopic plants which obtain their energy via photosynthesis. They are important to the aquatic ecosystem because they are part of the primary producing community and assist in recycling elements such as carbon and sulphur which are required elsewhere in the community . They live suspended in the water environment, and form a very important part of the freshwater community. They move via convection or wind induced currents. In almost every habitat of a freshwater ecosystem, thousands of these organisms can be found, and due to their small size and simplicity, they are capable of occupying large expanses of water and multiplying at an exponential rate.
