Name _____________________________________________________________________ Plankton: Phytoplankton Zooplankton General Description Size How do they make energy? Are they plankton their whole life? Other things of note? Where do we find plankton in the water column? Why do we find them there? Name ________________________________________________ Plankton Background Reading Background The word plankton is from the Greek word for "wandering". Although many of these organisms have some form of locomotion, they cannot move against the stronger oceanic currents that move them along. Some planktonic organisms can be quite large (like jellyfish); however, most are small enough that they have to be viewed under a microscope to be identified. Plankton that can photosynthesize are called phytoplankton and form the basis of oceanic food chains. Zooplankton are made up of tiny animals that feed on other plankton. Organisms that spend their whole lives as plankton are called holoplankton. Others that spend only part of their lives as plankton are called meroplankton. Most marine organisms are meroplankton and start out their lives as eggs and larvae dispersed by the currents. The majority of photosynthesis and oxygen production occurs by phytoplankton in oceanic waters. Marine phytoplankton are also the first link in many marine food chains. Like terrestrial plants, phytoplankton utilize energy from the sun and nutrients from the water to produce food. Because they utilize sunlight, plankton growth and reproduction occurs in surface waters and is dependent upon the replenishing of nutrients in those waters through seasonal processes called runoff and upwelling, both of which often occur along coastlines. When the nutrients and sunlight are plentiful, phytoplankton may reproduce rapidly and a bloom may occur. With an increase in phytoplankton, zooplankton populations increase, often creating a chain reaction felt throughout the food web. About 90% of the world’s fisheries occur in rich coastal areas because of the high densities of plankton that grow in these areas. All plankton must avoid sinking. Phytoplankton require sunlight for photosynthesis, so they must stay within the photic zone, usually the top 100 meters of water. Zooplankton depend on phytoplankton and other zooplankton for food, so they must avoid sinking as well to stay near their food source. Plankton avoid sinking through increased surface area. Flattened bodies and appendages, spines, and other body projections slow sinking by adding surface area without increasing density. Some phytoplankton also avoid sinking by forming large chains. The use of low-­‐density substances like oil or fat helps increase buoyancy and can serve as food reserves for some species.
