Question

What kind of oxygen make life suitable on earth

Answer 1

The air that is inhaled is about 20-percent oxygen, and the air that is exhaled is about 15-percent oxygen, so about 5-percent of the volume of air is consumed in each breath and converted to carbon dioxide. Therefore, a human being uses about 550 liters of pure oxygen (19 cubic feet) per day.

Breathing 100 percent oxygen would be good for us -- but actually it can be harmful. So, the short answer is, pure oxygen is generally bad, and sometimes toxic.

So it can be concluded that impure oxygen makes life suitable on earth as pure oxygen is toxic.

and
Life is possible on the Earth because of the following reasons:
1). Presence of essential elements:The earth has essential elements like carbon, hydrogen, nitrogen and oxygen. These elements combine to form proteins- the building blocks of life.
2). Presence of oxygen: Life cannot survive without oxygen. The Earth has a large amount of oxygen in the air.
3). Presence of water: Water is also essential for life. The Earth has vast reserves of water. Water regulates body temperature and also helps in processes like digestion, excretion, etc.
4). Presence of atmosphere: The atmosphere has a protective layer of ozone gas which saves the Earth from harmful effects of ultraviolet radiation from the sun.
5). Temperature of Earth: The Earth’s distance from the sun gives it the right temperature for the development of life-forms. If there were even a ten percent increase or decrease in the distance from the sun, the Earth would have been a cold or hot desert.
6). Right amount of mass and gravitational force: The Earth has the right amount of mass. This mass produces strong gravitational force. This force holds the atmosphere intact.
