The pelagic zone of the ocean is the area of the ocean that is neither close to the bottom nor close to land. There are a wide variety of organisms that inhabit the pelagic zone. Phytoplankton float along the surface, using photosynthesis to produce food. Zooplankton are tiny organisms that float in the surface waters and feed on the abundant phytoplankton. Krill, small crustaceans, also feed on phytoplankton. They display vertical migration in which they swim at deeper depths during the day and then come up to the surface

Microbes

Microbes are microscopic living organisms that can only be detected with the help of specialized laboratory equipment called a microscope. These living organisms are so small that they are not visible to the naked eye.
