Original - "Prochlorococcus" Ecology P. marina is Earth's smallest plant. It is typically present at a density of on the order of a hundred thousand individuals per milliliter in the ocean. It sequesters ∼25% of the global CO 2total. P. ubique is one of the ocean's most abundant microbes dominates the microbial loop.

Edit - "Prochlorococcus"

Despite Prochlorococcus being one of the smallest types of marine phytoplankton/bacteria in the worlds oceans, its substantial number makes it responsible for a major part of the oceans’ and world’s photosynthesis and oxygen production. The size of Prochlorococcus (i.e. around 0.5 to 0.7 micrometers in diameter) and the adaptations of the various ecotypes allow the organism to grow abundantly in low nutrient waters such as the waters of the tropics and the subtropics (~40N to 40S), however they can be found in higher latitudes as high up as 60° degrees north but at fairly minimal concentrations and the the bacterias distribution across the oceans suggest that the colder waters could be fatal to it. This wide range of latitude along with the bacteria’s ability to survive up to depths of 100 to 150 meters i.e. the average depth of the mixing layer of the surface ocean, allows it to grow to enormous numbers, up to 3 octillion individuals worldwide. This enormous number makes the Prochlorococcus play an important role in the global carbon cycle and oxygen production. Along with Synechococcus(another species of cyanobacteria that coexits with prochlorococcus) these cyanobacteria is responsible for approximately 50% of marine carbon fixation, making it an important carbon sink via the biological carbon pump(i.e. the transfer of organic carbon from the surface ocean to the deeep via several biological, physical and chemical processes). The abundance, distribution and all other characteristics of the Prochlorococcus make it a key organism in oligotrophic waters serving as an important primary producer to the open ocean food webs.
