Answer 2

Answer:

The swimming macroscopic animals in an ‘aquatic environment’ are referred to as Nekton.

Explanation:

The term nekton was proposed by German researcher Ernst Haeckel to separate between the dynamic swimmers in a waterway, and the uninvolved living beings called as plankton.

As a rule, nektonic living beings have a high Reynolds number (more noteworthy than 1000) and plank tonic life forms a low one (under 10). It is a matter of fact that, a few living beings can starts life as plankton and progress to nekton later on in their life cycle.
