Marine Life Plankton And Primary Production Main Concepts

Marine Life Plankton And Primary Production Main Concepts Main concepts: primary productivity primary production is the conversion of nutrients with sunlight or chemical energy into carbohydrates by certain organisms photosynthesizing organisms are primary producers, or autotrophs primary producers form a critical link between the living and nonliving worlds and form the base of all marine communities types of primary producers include microalgae. Ocean productivity largely refers to the production of organic matter by " phytoplankton," plants suspended in the ocean, most of which are single celled. phytoplankton are " photoautotrophs.

Marine Life Plankton And Primary Production Main Concepts The organisms responsible for primary production are called primary producers or autotrophs. most marine primary production is generated by a diverse collection of marine microorganisms called algae and cyanobacteria. together these form the principal primary producers at the base of the ocean food chain and produce half of the world's oxygen. Phytoplankton are the primary producers of the marine ecosystem and are the first link in the marine food web. extraordinarily, these microscopic phytoplankton account for up to half of the total global primary production on planet earth and have been critical in producing our oxygen rich atmosphere. all phytoplankton are single celled. Abstract. marine photosynthetic plankton are responsible for approximately 50 peta grams (1015) of carbon per year of net primary production, an amount equiv alent to that on land. this primary production supports essentially all life in the oceans and profoundly affects global biogeochemical cycles and cli mate. This chapter describes how the approaches listed in table 2 are used to gain an understanding of primary production and phytoplankton ecology in the open sea. the chapter starts by describing the main types of phytoplankton from both taxonomic (section “phytoplankton diversity”) and functional (section “plankton functional groups and trait based phytoplankton ecology”) perspectives.

Phytoplankton are the primary contributors to marine productivity 1, fixing roughly 45 gigatons of carbon each year 2.like other organisms, both terrestrial 3 and marine 4, phytoplankton are. Photosynthetic microbes, collectively termed phytoplankton, are responsible for the vast majority of primary production in marine waters. a synthesis of the latest research suggests that two broad.
