Document Summary
Organisms require resources and condiions (abioic) most important. Certain organisms perform beter (i. e. maybe their metabolism performs beter) in certain environments (ranges of tolerance) S (lethal zones) are dealy and organisms cannot survive in these areas. For plants two main factors are temperature and soil moisture (most important) Other factors are less important (secondary importance) Three main elements important to plants(nitrogen, phosphorus, potassium) More air rises at the equatorial region , doesn"t stay there. Coninuous warm air pushes other warm air packets up to the atmosphere which is then pushed and squeezed north and south where it is no longer pushed by other air and then begins to descend at this point. Do not get any precipitaion out of this process (at 30 degrees north and sound) as the precipitaion has been drained out of it already. At +/- 30 degrees, very dry desert-like environment. Weight of the air itself causes pressure in the atmosphere.
