How does thelinthospere hydrosphere and atmosphere individually and collectively affect the biosphere?

Atmosphere creates biOSphere many ways. Atmosphere heaving natural greenhouse effect has made biOSphere by increasing the average global temperature from - 18 degree C to 15 degree C. Atmospheric pressure (1atm) makes us not to be suspended in air : Atmospheric O2 (20.9%) supports respiration of biota to survice; atmospheric CO2(365ppm) is a essential for photosynthesis by plant, parimary source of food-chain for animal and human.
