Solution
The correct option is C Plankton
- Planktons are those organisms that live suspended in the water column and are lacking locomotory ability to be able to swim counter to typical ocean currents. They include phytoplankton, zooplankton and bacteria.
- Nektons are those animals that move in the water column, but are
capable of more powerful swimming and can move against a current or through turbulent water. They range from small fish, to the largest whales.- Sestons are minute materials moving in water and including both living organisms (such as plankton and nekton) and nonliving matter (such as plant debris or suspended soil particles).
- Pleustons are organisms living in the thin surface layer existing at the air-water interface of a body of water.
