Taxonomy and Producers

Phylum Anthrophyta -Submergent plants *lives entirely underwater *seagrasses -Emergent Plants *roots underwater; rest of plant above water *mangrove trees
BOTH Submergent and Emergent plants -contribute food to ocean's biosphere -produce oxygen - provide habitats for organisms - must adapt to salinity in water
Cyanobacteria= blue-green algae -major producers -aquatic & unicelluar -photosynthetic -prokaryotic cells *no true nucleus
Phylum Phaeophyta= brown algae *Holdfast- anchors the plants *blades (like leaves) *Pneumatocyst: gas-filled bladders *ex: kelp (largest type) *ex: Sargassum (huge drifting rafts of brown algae)
Phylum Rhodophyta= red algae *important to coral reefs because it helps cement the reef together *Phycoerythrins- red pigment which allows red algae to live deeper in the water
Phylum Chlorophyta= green algae *Chlorophyll a- absorbs different colors of light and used for photosynthesis *Chlorophyll b- helps to capture light -cell walls made of cellulose -ex: sea lettuce
Phylum Dinophyta= dinoflagellates *use flagella to swim *cause of toxic red tide *2nd most productive group of primary producers
Bioluminescence *the production and emission of light by a living organism as the result of a chemical reaction during which chemical energy *Found in the phylum dinophyta (pyrrophyta) *90% of deep-sea marine life is estimated to produce bioluminescence in one form or
Phylum Chrysophyta (Bacillariophyta)= diatoms *most productive phytoplankton *cell walls made of silica *Diatomic Blooms- sudden increase of diatoms *Blooms usually happen in the summer when there is an increase in nutrients
Sargasso Sea -Nuestonic community-organisms that float on top of the water *drifting rafts of sargassum (brown algae) *found in the North Atlantic Ocean *a biotic factor of it is that it creates habitats for animals such as sea turtles and fish *Abiotic factors ar
