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 … See more Most of the solar energy reaching the Earth is in the range of visible light, with wavelengths between about 400-700 nm.

Photic Definition & Meaning Dictionary.com
WebThe euphotic zone is the layer of water in which there is enough light for net photosynthesis. In other words, the rate of photosynthesis is faster than the rate of respiration (Fig. 2.42). There is an overall net production of oxygen in the euphotic zone. In clear tropical waters, the euphotic zone may extend to a depth of 80 meters (m).

WebThe euphotic or photic zone forms the uppermost layer of the ocean receiving the sunlight using which the phytoplanktons undergo the process of photosynthesis. Most aquatic life resides in this zone as it is the layer with abundance of sunlight. Webadj 1. (Biology) characterized by or growing in the absence of light: an aphotic plant. 2. (Physical Geography) of or relating to the zone of an ocean below that to which sunlight can penetrate, usually about 90m (300 ft).
