Document Summary

Material transfered: carbon c water h2o nitrogen n phosporos p sulphur s oxygen o. Biogeochemical cycling: transfer of material within and between ecosystems. Ecosystems: 1 or more communities of living organisms interaccting. Bc: transfer -> output ecosystem a input ecosystem b. In non living matter (rock, air, water) about . 032% carbon. 4 pools of carbon on earth: terrestrial pool (land, all vegated & non-vegatated land surfaces & associated soil, animal, bacteria, fungi, parasites. Increases or decreases: earth"s crust, largest pool of carbon, 100 billion gt. 2 trillion pounds: 4000 gt fossil fuel: old dead animals that under temp & pressure become coal, gas, oil, etc, dead carbon. Then 102 t/yr respiration: fossil fuel burning/ biomass burning, use of old dead carbon animals and plants to make coal, oil, gas, carbon fluxes -> long time, post indust. Every year we put more co2 into the atmospere. Parts per million (ppm) = carbon dioxide (night) 50 gt plants.
