Sc = 500/0. 085 = 5,882: pc 5882/0. 06 = 98033. 3333, pp = 98039/0. 15 = 653593. 3333. Introduction to nutrients cycling: cycle of nitrogen, cycle of phosphorous (also read 556-559, acid rain and the cycle of sulfur. *builds our understanding around 2 kinds of fluxes: biological flux (decomposition, physical flux (weathering) Trying to encompass different reservoirs - trying to understand all of the fluxes (what"s linking things together?: reservoir or pool - characterized in terms of amount of material it contains (a unit of mass) ex. Primary producers are a reservoir of n, the atmosphere is a reservoir of c (as. Fluxes - are the movement of material from one reservoir to another (units of mass/time) Some ecosystems reply almost exclusively on recycled nutrients whereas others rely on nutrients from outside ____________: ecosystem analysis: adopts a mass balance approach: Input (to the system) - output (to the system) = change in storage. If you know them, can calculate change in reservoirs.
