We now have fertilisers which are sprayed in large quantities on crops which make the plants grow very well
Answer:
Plants and other creatures utilize photosynthesis to convert light energy into chemical energy, which is then released to power the organism's metabolic processes through cellular respiration.

We inhale air that is comprised of roughly 78 percent nitrogen and 21 percent oxygen, as well as a trace amount of other gases.
When we exhale, the components are the same, they just come out in different amounts. Exhaled air is made up of about 78 percent nitrogen, 18 percent oxygen, and four percent carbon dioxide, excluding those trace gases.
TL;DR
Inhaled: 78% Nitrogen, 21% Oxygen, 1% Other Gases
Exhaled: 78% Nitrogen, 18% Oxygen 4% Carbon Dioxide
The carbon cycle illustrates the central importance of carbon in the biosphere. ... During this process, plants cleave the carbon from the two oxygen molecules and release the oxygen back into the surrounding environment. Plants are thus primarily responsible for the presence of atmospheric oxygen.
