Answer to Question 1

Marine organisms can be classified according to where they live (their habitat) and how they move (their mobility). Organisms that inhabit the water column can be classified as either plankton (drifters) or nekton (swimmers). All other organisms are benthos (bottom dwellers). Plankton can be classified based on their feeding styles. If an organism can photosynthesize and therefore produce its own food, it is termed autotrophic. Autotrophic plankton are called phytoplankton and can range in size from microscopic algae to larger species of drifting kelp. If an organism cannot produce its own food and relies instead on food produced by other organisms, it is termed heterotrophic. Heterotrophic plankton are called zooplankton, which includes drifting marine animals.
