WebJan 16, 2024 · The sunlit zone is also known as the photic or the euphotic zone in the ocean. This sunlit zone is the region of the ocean water that receives the most light from the sun. It’s important to the oceans because it helps carry out photosynthesis and feed most of the marine animals. WebBy some estimates, about two-thirds of all the photosynthetic activity that occurs on Earth (on land and in the water) takes place within the euphotic zone. Below the euphotic zone to a depth of about 3000 m is the layer known as the dysphotic ( “ dys- ” = poor) zone.

Web1. Introduction [2] Euphotic zone depth, z 1%, reflects the depth where only 1% of the surface photosynthetic available radiation (PAR) remains [Kirk, 1994]. z 1% is a measure of water clarity, which is not only a quality index of an ecosystem but also an important property for primary production [Behrenfeld and Falkowski, 1997; Platt and Sathyendranath, 1988] and … WebII. Vertical life zones of the oceanic zone. A. Neustic zone: the thin film or “skin” formed by surface tension at the surface of the water. B. Euphotic zone: The top of the water column as far down as light is available for photosynthesis.

The photic zone, euphotic zone, epipelagic zone, or sunlight zone is the uppermost layer of a body of water that receives sunlight, allowing phytoplankton to perform photosynthesis. It undergoes a series of physical, chemical, and biological processes that supply nutrients into the upper water column. The photic … See more In the photic zone, the photosynthesis rate exceeds the respiration rate.
