It extends from the tropics to the polar regions and from the sea surface to the abyssal depths. The bathyal zone is in permanent darkness, with only a tiny amount of sunlight at the blue end of the spectrum penetrating as far down as the bathyal zone. The statement that correctly lists the three zones that further divide the open-ocean zone is "deep zone, surface zone, transition zone." We are talking about the part of the ocean that is way ahead from the shores. The upper 200 m of the ocean is termed the photic zone. The sunlight zone, twilight zone, and deep ocean are the three major zones of the ocean. UN-2.

The Epipelagic zone is the most ideal zone for life as it does not face extreme challenges such as high pressure or freezing temperatures. Separated into epipelagic, mesopelagic, bathypelagic, abyssopelagic and hadopelagic subzones, areas in the pelagic zone are distinguished by their depth and the ecology of the zone. In which zone would you find very little plant or animal life compared to other zones? Ninety percent of all marine life lives in the upper zone of the ocean that receives sunlight.The open ocean is home to numerous types of plankton. 2 votes. Bathypelagic Zone [Midnight Zone] This zone extends from mesopelagic zone at about 1000 meters (3,280 feet) to a depth of about 4000 meters (13,123 feet). As a result, the open ocean supports fewer organisms. The ocean is a huge body of saltwater that covers about 71 percent of Earth's surface.
