Document Summary
Biogeochemical cycles: chemical elements are continually recycled with ecosystems, We will focus on 4 major biogeochemical cycles. For ea(cid:272)h o(cid:374)e, take (cid:374)ote (i) biological importance (ii) forms in which each chemical is available (iii) major reservoir for each chemical (iv) key process that rive the cycle. Key process that importance each chemical is for each chemical drive the cycle available. Co2 is taken up based converts co2 to fuels, and and released molecules organic molecules sediments, through solutes in oceans, photosynthesis plant and animal and respiration; biomass, the volcanoes and atmosphere, and burning of fossil sedimentary fuels rocks. Binds with soil cycle found in nucleic the most important are sedimentary particles, acids, inorganic form of rocks or marine movement is phospholipids, phosphorus and atp often localized origin, the oceans, and organisms. + by nitrogen is the back to n2 proteins and ammonification, nucleic acids and nh4.
