an absence of a limnetic zone and the littoral zone spans the entire lake. Together, these two zones comprise the photic zone. There are two main sources...

organism's eyes are used to convert blue light from the photic zone or green bioluminescence in the aphotic zone into red light to aid vision. A new fluorophore...

demersal zone is variable in depth and can be part of the photic zone where light can penetrate, and photosynthetic organisms grow, or the aphotic zone, which...

The water column is further divided into zones based on depth and the amount of light present. The photic zone starts at the surface and is defined to...

sublittoral zone refers to the areas where sunlight reaches the ocean floor, that is, where the water is never so deep as to take it out of the photic zone. This...

Day length and insolation intensity also control the extent of the photic zone. Subsurface productivity is limited by nutrient availability, as the...

matter export is driven by high levels of primary production in the photic zone, supported by a continual supply of nutrients to the oxic surface waters...
