The pelagic region is divided into three zones. ... This is the ocean zone that sunlight penetrates. Because this zone gets sunlight, photosynthesis can occur and plants can grow here . The sunlit zone
How does light affect the ocean?
When sunlight strikes the ocean, some of it reflects off the surface back into the atmosphere . The amount of energy that penetrates the surface of the water depends on the angle at which the sunlight strikes the ocean. Near the equator, the sun’s rays strike the ocean almost perpendicular to the ocean’s surface.
Does sunlight affects the life zones in the ocean Why or why not?
Sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet). ... Sunlight does not penetrate to these depths and the zone is bathed in darkness.
Which ocean zone does not get sunlight?
54% of the ocean lies in the Bathypelagic (aphotic) zone into which no light penetrates. This is also called the midnight zone and the deep ocean. Due to the complete lack of sunlight, photosynthesis cannot occur and the only light source is bioluminescence.
What are the 3 zones based on sunlight?
The importance of light in the ocean is reflected by the description of the ocean’s vertical zones of the water column in terms of how much light these zones receive. The ocean is generally divided into three zones which are named based on the amount of sunlight they receive: the euphotic

Which ocean zone has the most sunlight?
Epipelagic Zone – The surface layer of the ocean is known as the epipelagic zone and extends from the surface to 200 meters (656 feet). It is also known as the sunlight zone
Do sharks live in the Twilight Zone?
Deep sea sharks live below the photic zone of the ocean , primarily in an area known as the twilight zone between 200 and 1,000 meters deep, where light is too weak for photosynthesis. ... The sharks in this zone feed primarily on other deep-sea creatures.
What are the 4 ocean zones?
Like ponds and lakes, the ocean regions are separated into separate zones: intertidal, pelagic, abyssal, and benthic . All four zones have a great diversity of species. Some say that the ocean contains the richest diversity of species even though it contains fewer species than there are on land.
Which ocean zone is the coldest?
(bathypelagic zone) Lowest ocean zone that has no light, little life, coldest temperatures, and the most pressure.
What fish live in the abyssal zone?
Anglerfish : Some species of this fish are considered demersal while others swim and live in the upper portions of the abyssal zone.
How deep is the abyssal zone?
The Abyssopelagic Zone (or abyssal zone) extends from 13,100 feet (4,000 meters) to 19,700 feet (6,000 meters) . It is the pitch-black bottom layer of the ocean.
What animals live in sunlight zone?
