The proportion of nitrogen in air remains the same due to the nitrogen cycle which ensures the equal input and equal consumption of nitrogen by plants and animals.

Interesting question.
Well, absolutely, all the essential-for-life natural elemental cycles are a beautiful, stable, balanced dance [but we must never take that for granted because, just like weather systems, they are probably inherently chaotic. (chaos does not mean instability- it means sensitivity to small changes under the right circumstances)].
What is often not appreciated is the action of buffers in keeping the proportion of *free* elements extremely stable.
Buffers are a negative feedback system where higher concentrations of an element increase the activity of the buffer which leads to lower concentrations of the element. Beautiful, isn't it :)
Buffers in the nitrogen cycle include leguminous plants which have a symbiotic relationship with nitrogen-fixing bacteria in their roots.
