Photic organisms
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. Webphotic zone, surface layer of the ocean that receives sunlight. The uppermost 80 m (260 feet) or more of the ocean, which is sufficiently illuminated to permit photosynthesis by …

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. WebKoninckoporaceans are probably photic algae, the assignment of which to the dasycladales is disputed, because of: (1) the gigantic size for an unicellular organism; (2) a type of wall very rare among the true dasycladales, except for Clypeina (see earlier); (3) an evolution of the wall from unilayered dark microgranulate to bilayered, with an …

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.
