The pelagic zone can be thought of in terms of an imaginary cylinder or water column that goes from the surface of the sea almost to the bottom. Conditions differ deeper in the water column; the pressure increases, the temperature drops and less light penetrates.he pelagic zone can be contrasted with the benthic and demersal zones at the bottom of the sea. The benthic zone is the ecological region at the very bottom of the sea.
Layers of the Pelagic Zone. The pelagic zone is an enormous column of water that extends from the surface to the bottom of the world's oceans, away from the shore. It can be divided into several layers, which differ in amount of light, temperature, pressure and dissolved oxygen.he organisms that make their home in the pelagic zone can be divide into three types, phytoplankton, zooplankton and nekton. Phytoplankton-these primary producers are the basis of the ocean's food chain.
