PLANKTON! The word plankton comes from the Greek word, planktos, which means to drift. + Plankton are at the base of the ocean food web. There are two basic types of plankton. 1. Plant like plankton: phytoplankton 2. Animal like plankton: zooplankton Phytoplankton How do phytoplankton obtain their food? Photosynthesis (energy from sun) or chemosynthesis The two most common types of phytoplankton are: DIATOMS Kingdom: Protista - A type of algae Cell walls made of silica (material ngdomgdom: Protista - A type of algae - Cell walls made of silica (material in glass) http://www.nhptv.org/natureworks/nwep6d.htm DINOFLAGELLATES/FLAGELLATES Kingdom: Protista - Two flagella - One wraps around cell and the other is used for navigation - Photosynthesis - Responsible for Red Tides Zooplankton How do zooplankton obtain their food? They are heterotrophs so they eat it/absorb it into their bodies Distinguish between the words holoplankton and meroplankton. - Holoplankton is plankton its whole life - Meroplankton is plankton for only part of its life What is nekton? Opposite of plankton; free swimming; can swim against currents - FORMANIFERA Sometimes called forams. Protista Have pseudopodia that go through pores to catch food Shells sink to bottom to form ooze Help form limestone and chalk RADIOLOARIANS - Protista Silica shells Spiny Pseudopodia to catch food Forms radiolarian ooze ZOOFLAGELLATES JELLYFISH CILIATES - Protista Hairlike projections called cilia Paramecium Crawl around on plants and other surfaces. SIPHONOPHORES - - Kingdom Animalia - Cannot swim against currents - Wash up on beaches easily. KRILL http://www.nhptv.org/natureworks/nwep6d.htm COPEPODS - Kingdom PLANKTON!
