In the region of the pelagic zone from the surface to 660 feet (200 meters), phytoplankton (algae and microscopic plants) live. They are the primary producers of the ocean, the lowest level on the oceanic food web.They use the process of photosynthesis to provide food for themselves and for higher organisms.n the region of the pelagic zone from the surface to 660 feet (200 meters), phytoplankton (algae and microscopic plants) live.
