centrally located on continents grow our crop plants windy rainy season and dry season fire bison and stuff animals

population trends
calculate pop density # of organisms in area
carrying capacity
max # of animals an area can support
pop crash
lots of animals die
exponential growth
assumes unlimited resources
humans show exponent
logistic growth
assumes there is a carrying capacity “S” curve
carbon cycle
change carbon from organic form into inorganic form (CO2)
photosynthesisi
respiration
decomosition
burnining fossil feuls
nitrogen fixation
certain bacteria in soil turn nitrogen gas into usable form (nitrates)
