Document Summary
Lecture 8: chapter 25 global ecology (a) Concept 25. 1 elements move among geologic, atmospheric, oceanic, and biological pools at a global scale: e. g. Nitrogen (n), carbon (c), sulfur (s), phosphorus (p: pool/reservoir amount of an element in a component of the biosphere, flux rate of movement of an element between pools, e. g. Terrestrial plants are a pool of carbon; photosynthesis represents a flux: e. g. Co2 and ch4: movement of c from the terrestrial pool to the atmospheric has increased greatly due to the anthropocene (human global extinction) Incl. deforestation and the burning of fossil fuels (cars, factories) Concept 25. 2 the earth is warming due to anthropogenic emissions of greenhouse gases: warming effects, and other associated forms of climate change will increase with the increase in. It will be so rapid, most species will likely not be able to adapt in time and dispersal will be key to survival.
