OCG 301 Lecture Notes - Lecture 14: Ocean Acidification, Coccolith, Frustule
Document Summary
First graph, chart of all plant mass. Also plays a substantial role in carbon cycling. Transformation of light energy into chemical energy for use in living cells. Organic matter synthesis also converts dissolved inorganic nutrients to organic matter (c:n:p =106:16:1) Ncp = gpp - rplants - ranimals. Gpp = rate at which carbon is fixed by photosynthesis. Foundation of the aquatic food web, feed everything from zooplankton to whales. Comprise less than 1% of photosynthetic biomass but are responsible for fixing roughly 50% of carbon made by photosynthesis on earth. Pictures of every single cell in 5ml sample. Important in food web, nutrient cycling, gene flow. Responsible for the majority of the respiration in the ocean. Osmotrophic; uptake of dissolved organic compounds by osmosis for nutrition) Responsible for a significant fraction of the remineralization of organic matter. Plants and bacteria require inorganic compounds to build organic.
