Question

Distinguish between biota of the pelagic and benthic zones of the oceans with examples.

Answer 1

Explanation:

As you see from the diagram,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 surface layers of a water body.

From the shallowest to the deepest are: the epipelagic (less than 200 meters), the mesopelagic (200–1,000 meters), the bathyal (1,000–4,000 meters), the abyssal (4,000–6,000 meters) and the deepest, the hadal (below 6,000 meters). The lower zones are in deep, pressurized areas of the ocean.
