actively moving organisms having well developed locomotive organism are called as​

Answer 1

Answer:

Nekton (or swimmers) are living organisms that actively swim and move independently of currents. Nekton are heterotrophic and have a large size range, with familiar examples such as fish, squid, octopus, sharks, and marine mammals.

The benthos live on the ocean floor or the bottom of a river, lake or stream. Starfish, oysters, clams, sea cucumbers, brittlestars and anemone are all benthos.

Phytoplanktons and zooplanktons are unable to swim against currents and thus drift in water.
