The oxygen content of the air effectively remains constant.

Explanation:

Plants photosynthesise to produce oxygen but this is not just in the vicinity of where the oxygen is needed by organisms. Plants all over the world produce oxygen, which circulates in the air. Thus the oxygen content in the air I s pretty stable at just below 21%.
