What happened of respiration if there is only oxygen in gases in earth
Answers
Explanation:
The lighter the molecules of a gas are, the faster the molecules can move. In the case of hydrogen in the atmospheric temperature range, some gaseous hydrogen molecules will move fast enough to exceed the earth's escape velocity and can thus escape from the earth's atmosphere into space.
Answer:
If there was no air on earth, plants and animals would not survive. The latter use oxygen for respiration, therefore they will not get the necessary fuel for the breakdown of the food products.
In addition, plants cannot make food in the absence of carbon dioxide. All life forms will cease to exist on the earth resulting in the planets becoming uninhabitable.
Moreover the ultra violet rays will fall on earth and cause untold destruction because the atmosphere will lack ozone layer.
