it is called the pelagic zone.
The benthic zone is a region at the lowest level of an ocean or lake. The intertidal zone is the shallowest part of the benthic zone.
The benthic zone covers about 70 percent of the surface of the Earth. It is the ecological region at the lowest level of a body of water.
Consumers in the benthic zone, called Zoobenthos, can range from starfish in the intertidal zone, to bottom-dwelling flatfish, to deep sea Rattails. The type of consumer is highly dependent on the specific areas in the benthic zone.
Benthic Zone
The question is slightly incorrectly phrased as 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.
The deepest part of the "benthic zone" for aqueous ecology is the "hadal" zone (6000 meters or more beneath the surface). It is also known as the hadopelagic or "trench zone" of deep-sea organisms.
You would fine sediment in the benthic zone, or bottom, of a lake.
Most benthos organisms live in the benthic zone of the ocean floor, which includes the seabed and the waters just above it. This region extends from the intertidal zone down to the deep sea, with a significant concentration found in continental shelves where sunlight penetrates, supporting diverse ecosystems. The benthic zone provides various habitats, from sandy and muddy bottoms to rocky substrates, fostering a wide range of life forms.
The littoral zone of a lake is the near the shore area where sunlight penetrates all the way to the sediment and allows aquatic plants to grow. The benthic zone is the region at the lowest level of a body of a lake including the sediment surface and some sub-surface layers.
Zooplankton require sunlight for photosynthesis to occur, which is not available in the aphotic zone. Additionally, the benthic zone is the seafloor region where zooplankton would not typically dwell due to lack of nutrients and food sources, as well as potential predation risks.
The two subzones making up the Benthic zone is the abyssal and hadal
