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 bo...
The 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. It includes the sediment surface and some subsurface layers. Marine organisms living in this zone, such as clams and crabs, are called benthos. The demersal zone is just above ...
Benthic and pelagic zones refer to the different regions within a body of water. In this ScienceStruck article, we shall study the important aspects of both these regions, and make a comparison between their attributes.
This amount will vary on the depth of the benthos, and the degree of benthic-pelagic coupling. The benthos in a shallow region will have more available food than the benthos in the deep sea. Because of their reliance on it, microbes may become spatially dependent on detritus in the benthic zone.
Benthic vs Pelagic Our atmosphere is divided into different atmospheric layers depending on the physiochemical properties of that particular zone, and many of us are quite familiar with those. Similarly, any water body can be divide into different zones, which are demarcated by their own physical and chemical properties, as well as arbitrary boundaries […]
Benthic zone. The benthic zone is the ecological region at the lowest level of a body of water such as an ocean or a lake, including the sediment surface and some sub-surface layers. Organisms living in this zone are called benthos, e.g. the benthic invertebrate community, including crustaceans and polychaetes.
A shark is a pelagic fish and lives mostly in the pelagic zone (although there are exceptions to this and some sharks live in the demersal zone for some periods too). Whereas stingrays are benthic fish , living on the seabed and are heavier than the surrounding water.
The 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. It includes the sediment surface and some subsurface layers.
The main difference between benthic and pelagic is that the benthic means relating to/occurring at the bottom of a body of water while pelagic means relating to/living or occurring in the open sea. Benthic zones are darker and colder while pelagic zones are lighter and warmer.
The Deep Zone. The water of this layer is colder and denser than in the other areas. The ocean is divided into three main areas: pelagic, demersal and benthic. Ocean zones by depth . It is more common to classify the ocean layers according to their depth because many species are categorized according to the depth zone where they inhabit.
