WebIn the well-illuminated upper zone or photic zone plants can photosynthesize. The pelagic flora falls into two main groups: the unicellular microphytoplankton and the large free … WebWithin the pelagic realm is the photic zone, which is the portion of the ocean that light can penetrate (approximately 200 m or 650 ft). At depths greater than 200 m, light cannot penetrate; ... The physical diversity of the ocean is a significant influence on plants, animals, and other organisms. The ocean is categorized into different zones ...

WebPlants of the photic zone. A wide variety of oceanic vegetation types and all types of plants can grow in the sunlit area. These plants include marine … 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. … See more 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, … 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-column stability. The spatial distribution of organisms can be controlled by a … 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 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 … 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 frustules. When diatoms die their shells can settle on the seafloor and become See more WebIn the aphotic zone, sunlight is virtually absent, but there can be light production from organisms (bioluminescence).
