(par 3. 3 ) Sedimentary and biological cycles – keeping nature circulated
In Nature everything is circulated. The two broad categories of global cycles are sedimentary and biological. A short but insightful article. http://www.libraryindex.com/pages/3191/Biogeochemical-Cycles.html The chemical elements that compose the Earth are not held in static compartments. The components of the atmosphere and oceans are transported by the fluid movements of these bodies, which determine our daily […]
(par 3. 3 ) Flow of nutrients, nitrogen, carbon and water through the ecosystem
(Sources: http://www.bbc.co.uk/schools/gcsebitesize/geography/ecosystems/index.shtml & http://en.wikipedia.org/wiki/Biogeochemical_cycle ) Ecosystem Cycles: Energy and Nutrient Transfers All ecosystems depend on two important processes: The flow of energy, and the recycling of nutrients. These processes take place in Energy and nutrient transfers. Such a transfer takes place in a biogeochemical cycle – a circuit or pathway by which a chemical element or molecule moves through […]
(par 3. 3 ) A graphic depiction of the Biogeochemical Cycles
http://homepages.nyu.edu/~pet205/biogeochem1.html BIOGEOCHEMICAL CYCLES Biogeochemical Cycle : the cycling of chemical elements required by life between the living and nonliving parts of the environment. Some examples of these chemical elements are H2O, P, S, N2, O2 and C. These elements cycle in either a gas cycle or a sedimentary cycle; some cycle as both a gas […]
