Similarly, at a depth of 10 meters, only one6 percent of solar power is present and about only 1 percent of alternative energy is present at a depth of 100 meters. Beyond 1000 metres, there has been no account of sunshine penetration. supported this, the ocean is split into zones called the euphotic zone (photic zone) , disphotic zone, and therefore the aphotic zone.
The euphotic zone is additionally called the photic zone for sunlight zone is that the uppermost layer which receives an ample amount of sunlight, this enables the phytoplanktons present on the surface of the water to perform photosynthesis. This zone extends from the surface all the way down to a depth where intensity falls to 1 per cent of that at the surface.
About 90 per cent of all marine life lives within the photic zone.
The disphotic zone is that the zone which extends from the bottom of the euphotic zone to about 200 metres below. The photic zone and also the disphotic zone together are called the epipelagic zone.
The aphotic zone is that the bottommost zone. It is present below the euphotic zone and it's been determined that almost all of the deep ocean waters belong to the zone.
