The benthic zone is the area near to the bottom of river, lake or sea. Most of the plants found there are algae and seagrasses, which are also called phytobenthos.Phytobenthos will occur more often in the superior levels of the benthic zone, since they depend on the sun for photosynthesis.ost of the plants found there are algae and seagrasses, which are also called phytobenthos.

Benthos are the organisms which live in the benthic zone, and are different from those elsewhere in the water column. Many are adapted to live on the substrate (bottom). In their habitats they can be considered as dominant creatures, but they are often a source of prey for Carcharhinidae such as the lemon shark.epending on the water-body, the benthic zone may include areas which are only a few inches below water, such as a stream or shallow pond; at the other end of the spectrum, benthos of the deep ocean includes the bottom levels of the oceanic abyssal zone.
