Document Summary
Temperature: 0 c - 50 c ph: 4 8 (these are the extreme boundaries) Most organisms have a well-defined range of tolerance: The optimum range of tolerance leads to the largest population: outside of this the number of animals/species found declines. This model however doesn"t take into account the biodiversity that is seen on earth. People, plants and fungi are more similar them some bacteria that look almost identical under a microscope (this is according to the chart) Frog species are still able to do very well in this environment. Less then 1mm of rain falls annually. The water is -2 c (the only reason that it is liquid is due to the large salt content which prevents it from freezing) Fish are still able to survive in these conditions. Liquid water (absolute requirement for life on earth) Redox chemistry: used to control energy flow: we are near the top of the redox chart.
