Answer:
The ocean is a vast habitat that is divided into several regions inclusive of the open water (pelagic zone), water near the ocean floor (demersal zone), and the ocean floor (benthic zone). The pelagic zone consists of the open ocean excluding areas near the coasts and sea floor. This zone is divided into five major layers marked by depth.
The mesopelagic zone extends from 200 to 1,000 meters (660-3,300 feet) below the surface of the ocean. This area is known as the twilight zone, as it sits between the epipelagic zone, which receives the most light, and the bathypelagic zone, which receives no light. The light that reaches the mesopelagic zone is dim and does not allow for photosynthesis. However, distinctions between day and night can be made in the upper regions of this zone.
