Ocean 100 Final – SDSU Latest Version Already Graded A Euphotic zone first 200 meters -where photosynthesis can take place -suns radiation can be absorbed Seed Plants -true plants -not very abundant -grasses, eelgrass and surfgrass -mangroves -like warm, muddy waters -have a root system Protists a) large algae(seaweed) -brown algae(kelp), green (sponge weed), red (rhodophyta) b) phytoplankton(small algae) -most producers -diatoms -coccolithophores -dinoflagellates Eukaryotes seed plants and protists Prokaryotes -ancient and very old -blue-green algae, cyanobacteria -first photosynthesizers, phytoplankton (chalk) -red algae is adapted to survive at greater depths (irish moss) regions of high productivity -polar regions -coasts -coral reefs polar regions -no thermocline -great amounts of sea life coasts -upwelling b/c eckman transport(winds moving water) -nutrients coming from land coral reefs very productive regions of low productivity -subtropical gyres -far from coasts -water doesn't move up or down -no upwelling -very high thermocline energy flow -Producers -Consumers producers -all photosynthetic -autotrophs-self surviving (produce their own food) consumers -all animals -heterotrophs -must consume other organisms (can't stay alive if they don't) vertebrates fishes, amphibians, reptiles,
