Document Summary
Abiotic factors that ultimately determine: where organisms live, resources available, rate at which population can grow. Places determine different rates (ie high altitude environment has an effect on where plants can grow, etc) Temperate rainforests = precipitation = different environment for organisms to live. Climate: long-term description of weather*, based on averages and variation measured over decades; includes daily and seasonal cycles, as well as yearly and decadal cycles. Chemical environment: the composition of soil, water, and air available in the environment. *weather: current conditions temperature, precipitation, humidity, cloud cover.
