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 wakors at night to eat. What is the relationship between zooplankton and krill? O Competition O Parasitism O Mutualism O Commensalism O Symbiosis

Classification of Marine Organisms

Classification is a way of categorizing organisms that enables an easy process of identification of such organisms. All living things are classified by grouping them under specific categories. The grouping is done based on the close relativeness of the organisms. The classification tool requires knowledge of characteristics, differences, and similarities between different organisms.
