Species
Bacteria
 Heterotrophic—most are decomposers
 Autotrophic---photosynthetic or
chemosynthetic
 No organelles
 Represent the smallest living organisms on
earth
 Reproduce rapidly (about twice an hour)
Prokaryotic producers
 Cyanobacteria---blue green algae
Can tolerate a huge change in salinity and
temperature
Some of these are nitrogen fixers
Protists

Diatoms
Dinoflagellates
Silicoflagellates
There are more but we discuss these
Diatoms






Eukaryotic
Photosynthesize
Reproduce sexually or asexual
12,000 species
They have silica shells called frustules
Called golden brown algae from the
pigment carotenoid

They have flagella
They spin
Unicellular
They have a primitive eyespot—sense light
They can be seen in the light
Cause algal blooms—red tide
Red tides
bioluminescence
 Produce light--
silicoflagellates
 Star shaped
 Have silica in their cell walls
 flagella

Phylum forminfera
Mostly marine
Shells of calcium carbonate
Psuedopods can retract
