Photic organisms
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.

WebThe Photic zone is the uppermost layer of the ocean that is bathed in sunlight during the day. It is broken into two different parts for location purposes: The Neritic zone and the Epipelagic zone. The Neritic zone, also known as the sublittoral zone, is the relatively shallow part of the ocean between the low tide mark and the continental shelf. 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

Some examples are polychaete worms, bivalves, echinoderms, sea anemones, corals, sponges, sea squirts, turbellarians and larger crustaceans such as crabs, lobsters and cumaceans. [8] Seagrass

Deeper water, where too little sunlight penetrates for photosynthesis, is called the aphotic zone. Surface water Surface water dissolves oxygen from the air, so there is generally plenty of oxygen in the photic zone to support organisms. sologenic to airdropWebOrganisms living in this zone are called benthos and include microorganisms (e.g., bacteria and fungi) [2] [3] as well as larger invertebrates, such as crustaceans and polychaetes.
