Organisms of the Pelagic Zone. The organisms that make their home in the pelagic zone can be divide into three types, phytoplankton, zooplankton and nekton. Phytoplankton-these primary producers are the basis of the ocean's food chain.pipelagic, or Sunlit Zone-this is the topmost layer of the pelagic zone, from the surface to a depth of about 200 meters (660 ft). It receives enough sunlight to support photosynthetic organisms such as seaweed and phytoplankton, and also has a high level of dissolved oxygen due to the action of the waves.
