Answer 2

Benthic zone is part of ocean layer which describes the layers closer to the bottom of the water body ,and pelagic zone is layer which includes the free water column that interacts with the surfaces layers of the water body.

Differences

Benthic: Referring to the sea, benthic zone start at the shoreline and extends into deep waters , away from landmass . It is noticed that there isnt specified depth to this zone ,as it could vary from few inches as in a stream to several 1000's of meters as in the open ocean. Since light cannot penetrate this depth, this zone lacks the ability to photosynthesis as its energy source.

Pelagic zone:: this zone is the uppermost layers of a water body ,especially referring to the ocean, interacts directly with the atmosphere .

Physical and chemical properties of this zone vary greatly because of the vastness of this area ,which extends from the uppermost waters down to the deeper layers near the benthic zone of a water column.

This zone can be divided into several sub layers that extend the top to bottom.
