Document Summary
Terrestrial plants and animals balance water loss against water intake. Marine and fresh water animals regulate water and salt diffusion depending on osmotic pressure. Precipitation and its timing, and humidity define biomes in north america. Cicadas sit most of the time on trees and make a lot of noise. They manage to sing (only if there are no predators). Most organists hide in the shade, go in the burrows under the stones, or generally become inactive. Saturation vapor density (g/m3) or pressure of water vapor graph. It simply means you can"t squeeze in any more. Any droplet you would put in, would fall on the ground. If humidity is high, it"s hard to sweat because the sweat does not evaporate. High saturation is at high temperatures. You can put many more grams of water into the atmosphere at higher temperatures. If you cool down the air temperature, the water has to return to wear it came from (liquid state).
