Introduction: Plankton
Plankton is a term used to collectively describe a wide variety of microscopic organisms that drift passively or swim weakly in bodies of water such as lakes, ponds or oceans. Though the individual organisms that make up plankton may be tiny, plankton plays a very important ecological role in both freshwater and marine communities.
