A pond ecosystem can be defined in three ways: A closed community of organisms in a body of water. This is called ecosystem. An ecosystemis a community of living organisms (plants, animals and microbes) in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system. The park is situated adjacent to Canoly Canal. Unit-VI: Environmental Pollution and Control. Ecosystem varies greatly in size from a small pond to a large forest or a sea.
