Document Summary
Fluxes: flows of matter into and out of reservoirs. Controlled by rates of transfer processes and capacities of reservoirs. Source: where the flux is coming from (source gives out more than it takes in) Sink: where flux is going (sink take sin more than it gives out) Negative feedback loop: self limiting: homeostatic cycle. Ecosystem ecology: study of interactions among organisms and their physical environment as an integrated system. Way of looking at organisms and their interactions with the environment as an integrated system. Focuses on functions, processes, fluxes, biogeochemical cycles etc. Can be studied on different spatial and temporal scales. Resistance: systems resist change and remain stable despite disturbance. Resilience: system changes in response to disturbance, but later returns to original state. Emergent properties= whole is more than the sum of its aprts. Stores 67 billion tonnes of carbon 303 years of carbon emissions. Npp: net primary productivity: energy available to consumers and decompsoers.
