Document Summary
Study of interactions among organisms and their physical environment as an integrated system. A way of looking at organisms and their interactions with the environment as an integrated system. Focuses on functions, processes, fluxes (energy, nutrients), biogeochemical cycles, etc. Inputs, outputs, feedback looks, resistance & resilience, emergent properties. Boundary between the biotic and abiotic components is often blurred. Why should we care about ecosystem ecology? provides mechanisms for basis for understanding the earth system provide goods and services to society human activities are changing ecosystems (therefore the earth system) Resistance= system resists change and remains stable despite a disturbance. Resilience= system changes in response to a disturbance, but later returns to its original state. Whole is more than the sum of its parts. Improve water quality, recharge ground water supply, pollination, co2 fixation, erosion control, pest control, medicine, nutrient retention and cycling. Stores 67 billion tonnes of carbon = 303yrs of carbon emissions carbon bank account = billion annually.
