Does the Benthic Zone Receive Sunlight?

The benthic zone begins at the shore and extends to the bottom of a waterbody. It is found all over the world. Only a small amount of sunlight reaches this zone. This zone is characterized by low temperature and high pressure.

Is there light in the benthic zone?

The benthic zone is the lowest level of a marine or freshwater system and includes the sediment surface, the water just above it, and some sub-surface layers. ... Because of the depths it can reach, the benthic zone is often characterized by low sunlight and low temperatures (Alldredge 1988).

How much sunlight is available in the benthic zone?

Beyond a depth of 1000 meters, light availability is almost zero, with photosynthesis no longer being feasible.
