HOW IS THE BALANCE BETWEEN OXYGEN AND CARBONDIOXIDE IS MAINTAINED?
Nature has all the sources to balance the exact composition of air.
Air is a mixture of several gases. The composition of air is as follows : nitrogen (78%) and oxygen (21%). The remaining 1% is other gases such as carbon dioxide, water vapour, hydrogen, argon etc. Every gas undergoes a cyclic process in the atmosphere wherein these gases are used and released by various organisms through different processes.Like plants and trees take CO2 released by living beings and living beings breathe in O2 released by plants and trees.The consistency maintained in the cycling of these gases leads to almost same percentage of these gases in the atmosphere.
