Water and the Atmosphere
Chapter 2 Lesson 4: Ocean Habitats 

   The ocean has three zones: intertidal, neritic, and open-ocean.  Each zone has its own conditions of submergence, light, and pressure.
   Marine organisms are classified according to where they live and how they move.  Plankton float, nekton swim, and benthos crawl or are attached to the ocean floor. 
All three types of organisms live in each of the three ocean zones. 
   A food web is a diagram of the flow of energy in an ecosystem.
