Explanation:

Jellyfish are classified as plankton. Plankton are organisms that drift in water and cannot swim against currents. Jellyfish lack the ability to actively swim long distances against water movement, fitting the plankton definition. Benthic organisms live on or in the bottom of a body of water. Nekton are free - swimming organisms like fish.
