Photic and euphotic zones
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 … 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. This is due to the abundant solar energy which is used as an energy source for photosynthesis by primary producers such as phytoplankton. These See more Due to biological uptake, the photic zone has relatively low levels of nutrient concentrations. As a result, phytoplankton doesn't receive … See more Most of the solar energy reaching the Earth is in the range of visible light, with wavelengths between about 400-700 nm. Each colour of visible light has a unique wavelength, and … See more • Mesophotic coral reef • Electromagnetic absorption by water • Epipelagic fish See more Ninety percent of marine life lives in the photic zone, which is approximately two hundred meters deep. This includes phytoplankton (plants), including dinoflagellates See more The depth is, by definition, where radiation is degraded down to 1% of its surface strength. Accordingly, its thickness depends on the extent of light attenuation in the water column. … See more Phytoplankton are unicellular microorganisms which form the base of the ocean food chains. They are dominated by diatoms, which grow silicate shells called See more

WebAs adjectives the difference between euphotic and photic is that euphotic is describing that part of the near-surface ocean in which photosynthesis is possible while photic is of, related to, or irradiated by light; especially describing that part of the near-surface ocean is which photosynthesis is possible. WebThe euphotic zone, or photic zone, is the area of the ocean surface in which enough light penetrates the water for the photosynthesis of algae and other photosynthetic plants to occur. The lower limit of this zone is determined …
