Photic organisms
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 enough nutrients when there is high water … 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 … See more Phytoplankton are unicellular microorganisms which form the base of the ocean food chains. They are dominated by See more

WebApr 7, 2024 · Euphotic zone organisms mainly include most of the ocean fishes like sharks and rays, man o war, jelly fishes, sea turtles, corals, seals and zooplankton. Some of these animals in this zone adapt to the technique of countershading. Countershading is done when an animal is light on its underside while dark on its upper parts. WebAquatic organisms generally fall into three broad groups: plankton, nekton, and benthos. They vary in how they move and where they live. Planktonare tiny aquatic organisms that cannot move on their own. They live in the photic zone. They include phytoplankton and zooplankton. Phytoplanktonare bacteria and algae that use sunlight to make food.
WebThe photic zone is the surface layer of the oceans or water bodies. This zone has enough light for organisms to carry out the process of photosynthesis. In the ocean, about 90% of life can be found and … WebJan 24, 2024 · Virtually all photosynthesizing organisms are distributed in the euphotic zone because without light there is no photosynthesis and, therefore, autotrophic beings cannot survive. The flora includes phytoplankton organisms, such as diatoms, cyanobacteria, chrysophytes, euglenophytes, dinoflagellates, among others.
WebApr 9, 2024 · The 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.
