What does the word plankton mean?
Wanderers
What is another term for autotrophs?
3
who consumes these autotrophs?
5
what does nekton mean?
Swimmers
What do accessory pigments do to aid plankton in photosynthesis?
7
Describe and identify: Phytoplankton
(Plant like) autotrophs in photic zone.
Describe and identify: Picoplankton
Extremely small (green) 100 million in every liter of seawater
Describe and identify: Diatoms
(Cut thru) most productive autotroph.Silicate shells. Contains accessory pigments to absorb more colors (including green)
- Single cell reproduce by division
- they eventually sink forming siliceous oozes
Describe and identify: Dinoflagellates
(Whirling whip)- single cell autotrophs. Contain whip-like flagella. Many are bioluminescent( converting chemical energy into light)
-responsible for harmful red tides
Describe and identify: Coccolithophores
Single cell autotrophs
Appear milky-white
Describe and identify: Zooplankton
Heterotrophic plankton
Describe and identify: Copepods
Larger shrimp like heterotrophs
Describe and identify: Holoplankton
Whole life as plankton
Describe and identify: Meroplankton
Early life as plankton
Where would you find the most productive waters and why?
Mid-latitude region
What is meant by the compensation depth and where does it occur?
2
What are the 2 usual limiting factors in photosynthesis reactions?
3
Regarding nutrients for plankton, what are the usual two?
5
What are plankton blooms?
Essential in the restoration of non-conservative nutrients and supports the continuation of photosynthetic productivity in the ocean ( most sink but gets brought back from upwelling)
Chlorophytes
Green color lacking accessory pigments
Phaeophytes
Tan color (kelp) Can grow up to 20 inches a day
Rhodophytes
Red ( accessory pigments) adapted to deep waters
Where are mangroves normally found?
Plants found in tropics, live in saltwater.
what type of waters are mangroves found in?
Saltwater
