Document Summary
Systems thinking is important because we"re concerned with inputs + outputs. Biogeochemical cycles = the way an element moves between different beings/locations in biological/geological/atmospheric reservoirs. Biogeochemical bio = living, geo = gases, chemical = chemical transformation. Substances move from these reservoirs and take on many forms. Size of reservoirs varies but the size of a reservoir + the rate of the cycle is affected by human activities. C, n, h, o, p, s take a variety of chemical forms weathering, erosion all recycle materials. The material goes from the source to reservoir to sink. Residence time = time the material remains in the reservoir. Flux = rate at which a thing moves through the system. The general biogeochemical cycle: 1) elements transform from organic to inorganic. 2) elements move through abiotic + biotic reservoirs. Water is an important reservoir it"s a transport medium in processes has effects on the.
