Ninety percent of marine life lives in the photic zone, which is approximately two hundred meters deep. This includes phytoplankton (plants), including dinoflagellates, diatoms, cyanobacteria, coccolithophores, and cryptomonads. It also includes zooplankton, the consumers in the photic zone. … Zobacz więcej 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, … Zobacz więcej Due to biological uptake, the photic zone has relatively low levels of nutrient concentrations. As a result, phytoplankton doesn't receive enough nutrients when there is high … Zobacz więcej 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 together they make up white light. The shortest wavelengths are on the violet … Zobacz więcej • Mesophotic coral reef • Electromagnetic absorption by water • Epipelagic fish Zobacz więcej 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 … Zobacz więcej 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 … Zobacz więcej Phytoplankton are unicellular microorganisms which form the base of the ocean food chains. They are dominated by diatoms, … Zobacz więcej WitrynaThe majority of organisms in the aphotic zone include sea cucumbers (phylum Echinodermata) and other organisms that survive on the nutrients contained in the dead bodies of organisms in the photic zone. Beneath the pelagic zone is the benthic realm, the deepwater region beyond the continental shelf.

WitrynaThe photic zone is the region in which the light intensity is sufficient for photosynthesis to occur. In the open ocean of tropical and subtropical regions, the photic zone is dominated by several ecotypes of the bacterium Prochlorococcus. Each ecotype dominates a particular depth range of the photic zone. WitrynaWater salinity, depth and whether the water is moving or standing. Explain why freshwater fish cannot survive in salt water. Salt water has high salinity and freshwater has low salinity. Give one reason why there tends to be more organisms in the photic zone than in the aphotic zone.
