The organisms responsible for primary production are called primary producers or autotrophs .

Feb 20, 2020 · The microzooplankton groups a large variety of organisms with only two common characteristics of size and apparent function. Microzooplankton are organisms of a size between 20 and 200 microns and are not obviously a phytoplankter (plant) of some kind. The grazing of microzooplankton is thought to be about 2/3 of the all phytoplankton produced ...
