Uh, fitoplanktoni su mnogo vise od jedne biljke
https://en.wikipedia.org/wiki/Phytoplankton#Diversity
The term phytoplankton encompasses all photoautotrophic microorganisms in aquatic
food webs. However, unlike terrestrial
communities, where most autotrophs are
plants, phytoplankton are a diverse group, incorporating
protistan eukaryotes and both
eubacterial and
archaebacterial prokaryotes.
There are about 5,000 known species of marine phytoplankton.
[28] How such diversity
evolved despite scarce resources (restricting
niche differentiation) is unclear.
[29]
In terms of numbers, the most important groups of phytoplankton include the
diatoms,
cyanobacteria and
dinoflagellates, although many other groups of
algae are represented. One group, the
coccolithophorids, is responsible (in part) for the release of significant amounts of
dimethyl sulfide (DMS) into the
atmosphere. DMS is
oxidized to form sulfate which, in areas where ambient
aerosol particle concentrations are low, can contribute to the population of
cloud condensation nuclei, mostly leading to increased cloud cover and cloud
albedo according to the so-called
CLAW hypothesis.
[30][31] Different types of phytoplankton support different
trophic levels within varying ecosystems. In
oligotrophic oceanic regions such as the
Sargasso Sea or the
South Pacific Gyre, phytoplankton is dominated by the small sized cells, called
picoplankton and nanoplankton (also referred to as picoflagellates and nanoflagellates), mostly composed of
cyanobacteria (
Prochlorococcus,
Synechococcus) and picoeucaryotes such as
Micromonas. Within more productive ecosystems, dominated by
upwelling or high terrestrial inputs, larger
dinoflagellates are the more dominant phytoplankton and reflect a larger portion of the
biomass.
