PELAGIC (planktons) Flashcards
cannot swim against the ocean current, they float in the water
plankton
two types of plankton
• phytoplankton
• zooplankton
two types of plankton
• phytoplankton
• zooplankton
microalgae (plant-like), uses sunlight for photosynthesis
creates oxygen, must stay on photic zones
phytoplankton
types of phytoplankton (5)
• diatoms
• dinoflagellates
• cyanobacteria
• coccolithophores
• desmidiales
types of phytoplankton (5)
• diatoms
• dinoflagellates
• cyanobacteria
• coccolithophores
• desmidiales
single celled, glass shell, responsible for carbon fixation and marine productivity
TRANSPARENT CELL WALL
diatoms
responsible for motility of cell or bacteria
causes red tide due to overpopulation, releases red plastids
dinoflagellates
blue-green algae, can be found in all types of water, responsible for OXYGENATION
cyanobacteria
unicellular, produce small calcium carbonate scales
responsible for marine carbon cycle
coccolithophores
freshwater photosynthesisers, food source for invertebrates
desmidiales
small aquatic microorganisms in the water column, heterotrophic planktons (consumers)
zooplankton
small aquatic microorganisms in the water column, heterotrophic planktons (consumers)
zooplankton
1 mm, cows of the sea
copepods
1 mm, cows of the sea
copepods
member of the crustacean order, same class of animal as crabs, lobsters, crayfish
grow 6cm, lives for 5 years
krill
free-swimming marine animals with umbrella shaped bells
jellyfish
free-swimming marine animals with umbrella shaped bells
jellyfish
small protozoan species, provide ammonia and carbon dioxide
radiolarians
small protozoan species, provide ammonia and carbon dioxide
radiolarians
type of amoeboid protest, exhibit an external shell and ectoplasm
foraminiferans
type of amoeboid protest, exhibit an external shell and ectoplasm
foraminiferans
can swim and move independently of currents, heterotrophic and large size
nektons
can swim and move independently of currents, heterotrophic and large size
