GENERAL KNOWLEDGE

Detailed explanation-1: -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.

Detailed explanation-2: -Epipelagic Zone. This surface layer is also called the sunlight zone and extends from the surface to 200 meters (660 feet). It is in this zone that most of the visible light exists. With the light comes heating from sun.

Detailed explanation-3: -The epipelagic zone is called the euphotic zone. This zone of the ocean is characterized by high light levels. This light is used to power photosynthesis. It extends from the surface of the ocean to a depth of about 200 meters.

Detailed explanation-4: -The epipelagic zone (or upper open ocean) is the part of the ocean where there is enough sunlight for algae to utilize photosynthesis (the process by which organisms use sunlight to convert carbon dioxide into food). Generally speaking, this zone reaches from the sea surface down to approximately 200 m (650 feet).
