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.

The benthic zone is the bottom-most layer of aquatic zones. What this zone appears like will ultimately depend on what type of benthic zone we are talking about. If you are describing a shallow lake, the benthic zone will still receive ample amounts of light. If you are talking about the oceanic benthic zone, then you will see little to no light here.
