Document Summary
Biogeography large-scale trends of living organisms (or dead that were once living: study of geographical distribution of organisms, habitats (ecological, historical and biological factors which produce them. Biodiversity on earth: btw 50-50 mill species of plants, animals and microbes, less than 2 mill have been formally described, more energy going into the system = more new species, along the equator, access to water. If theory withstands empirical tests, then it is considered corroborated but can never be proven true. Laws to know: td laws 1 and 2, 1 = energy cannot be created or destroyed. 2 = something about disorder trying to: law of geography, four laws of ecology, nature knows best, everything is connected to everything, no such thing as a free lunch, everything must go somewhere. Why is the theory of plate tectonics, not a law: 5-10km down where there"s a layer to hot for people to reach that layer, so we cant collect connect evidence.
