Abstract

Marine organisms can be categorized as benthic, planktonic or nektonic depending on their physical habitat and their mode of motility. Planktonic organisms are those that live suspended in the water column and that are sufficiently small and/or slow so as to be incapable of directed swimming. Thus, their distribution is considered to be controlled by physical processes, such as water currents and turbulent mixing. In addition, plankton can be divided further based on their nutritional modality. Autotrophic phytoplankton depends on light and chlorophyll to fix carbon dioxide into organic molecules, whereas heterotrophic zooplankton ultimately depends on the phytoplankton for their dissolved or particulate foodstuffs.
