Photic level
WebThis interval from the surface to 650 ft (200 m) is therefore known as the euphotic ( “ eu- ” = good, “ photo- ” = light) zone, or simply the photic zone. By some estimates, about two-thirds of all the photosynthetic activity that occurs on Earth (on land and in the water) takes place within the euphotic zone. WebLight may be detected as far as 1,000 meters down in the ocean, but there is rarely any significant light beyond 200 meters. The ocean is divided into three zones based on depth and light level. Although some sea creatures depend on light to live, others can do without it.
