  2. Marine biogeochemical cycles - Wikipedia

    en.wikipedia.org/wiki/Marine_biogeochemical_cycles

    The second sulfur sink is pyrite burial in shelf sediments or deep seafloor sediments (4 × 10 13 g/year; δ 34 S = -20‰). [94] The total marine sulfur output flux is 1.0 × 10 14 g/year which matches the input fluxes, implying the modern marine sulfur budget is at steady state. [93] The residence time of sulfur in modern global oceans is ...

    Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea. Given that in biology many phyla , families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy .

    en.wikipedia.org/wiki/Marine_food_web

    A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton. The second trophic level (primary consumers) is occupied by zooplankton which feed off the phytoplankton. Higher order consumers complete the web.

  8. Marine microorganisms - Wikipedia

    en.wikipedia.org/wiki/Marine_microorganisms

    In marine environments, microbial primary production contributes substantially to CO 2 sequestration. Marine microorganisms also recycle nutrients for use in the marine food web and in the process release CO 2 to the atmosphere. Microbial biomass and other organic matter (remnants of plants and animals) are converted to fossil fuels over ...
