Which zone is known as the Sunlight Zone, extending from the surface to about 200 meters?

Explanation:
Light can penetrate here enough to power photosynthesis, making this the zone where most of the ocean’s primary production happens. That upper layer, down to about 200 meters, is known as the Epipelagic Zone, the Sunlight Zone. Because light drives photosynthesis, phytoplankton thrive there and form the base of the marine food web, supporting a rich array of surface-dwelling and mid-water organisms. As you go deeper past roughly 200 meters, light fades and photosynthesis drops off, which is why the deeper Twilight Zone begins in the Mesopelagic, while the Abyssopelagic and deeper zones are dark and much colder. The Benthic Zone refers to the ocean floor, not the sunlit water column.
