Upper part of sea/aquatic ecosystem contains

1. plankton
2. nekton
3. plankton and nekton
4. benthos

Correct answer: plankton and nekton

Solution

The upper part of an aquatic ecosystem includes organisms in the water column: plankton drift near the surface, and nekton actively swim there too. Benthos live on or in the bottom, so they are not part of the upper zone.
