Answer 1

Answer:

a

Explanation:

The photic zone or euphotic zone is the depth of the water in a lake or ocean, that is exposed to such intensity of light at which the rate of oxygen consumption, is equal to the rate of carbon dioxide production. It extends from the surface down to a depth where light intensity falls to one percent of that at the surface, called the euphotic depth. About 90% of all marine life lives in the euphotic zone.

The zone which extends from the base of the euphotic zone to about 200 metres is called as the disphotic zone. While there is some light, it is insufficient for photosynthesis. The euphotic zone together with the disphotic zone coincides with the epipelagic zone. The bottommost zone, below the euphotic zone, is called as the aphotic zone. Most deep ocean waters belong to this zone.
