The next desired advancement in research is to estimate the primary production associated with distinct groups forming the entire primary producer community. Only a few recent studies have focused on group‐specific primary production modeling and were dedicated to regional applications [ Claustre et al. , 2005 ; Kameda and Ishizaka , 2005 ; Hirata et al. , 2010 ]. PAR incident on land. Even though primary producers in the ocean are responsible for nearly half the total NPP, they represent only 0.2% of the global producer biomass.

So phytoplankton are found close to the ocean surface. The two principal categories of producers in the sea are pelagic phytoplankton and benthic microalgae and macroalgae. Benthic plants grow only on the fringe of the world’s oceans and are estimated to produce only 5 to 10 percent of the total marine plant material in a year. Primary production • The production of organic compounds from atmospheric or aquatic carbon dioxide, principally through the process of photosynthesis (or chemosynthesis) • Carried out by autotrophs • On land primary producers are mostly macroscopic • In the sea nearly all primary production is by microscopic phytoplankton All life depends ultimately on primary producers, the organisms which capture the energy in sunlight by photosynthesis.

1. Introduction [2] Our understanding of oceanic biogeochemical cycles has benefited greatly from the recent advent of ocean color remote sensing.

Photosynthetic organisms like seaweed, zooxanthellae (algae living in coral tissue), and … The organisms responsible for oceanic primary production include a wide diversity of marine plants and algae. While many people may be more familiar with the larger seagrasses and macroalgae (seaweeds), by far the greatest amount of photosynthesis in the ocean … Cyanobacteria are dominant primary producers in their ecosystems, and are distributed worldwide, not only in the sea and fresh water, but also on land (Carpenter and Romans 1991;Potts 2000; Knoll Paleozoic primary production is described in detail. Microfossil and biomarker molecules both suggest that green algae played a greater role in marine primary production than they have in the past 100 million years, and biomarkers also suggest a significant role for … ocean ecosystems the source of energy is sunlight that drives photosynthesis done by micro- (phytoplankton) or macro- (seaweeds) algae, green plants, or photosynthetic blue-green or purple bacteria. These organisms produce ecosystem food that supports the food chain, hence they are referred to as primary producers.
