Nitrogen as an element isn’t created or destroyed outside of a nuclear reaction. So the amount of nitrogen on the planet is basically all we’ll ever have. Nitrogen does exist in various forms, though, and it’s the interconversion between these chemical forms that’s critical for life as we know it. We’re all composed of nitrogen. It’s part of every protein. It’s literally in our DNA. We need to eat nitrogen compounds (e.g., protein) to maintain our bodies, and we get rid of excess, or metabolized, nitrogen in our pee — mostly in the form of a compound called urea but there’s also a small amount of ammonia in pee too. So you could say we consume nitrogen in complex forms (protein, DNA, etc.) and produce nitrogen in simpler forms (urea, ammonia, uric acid). Bacteria and plants consume these simple forms and convert them back into complex forms. In the case of plants this is done using solar energy. There are soil and aquatic bacteria capable of converting nitrogen gas in air into nitrates and nitrites, which can then be used by plants. But for the most part, nitrogen in the air is fairly non-reactive and isn’t consumed by living things.

meaning this is why Pyrazole is so effective against bacteria, because it jams it up, similar to toxic mushroom to the liver.
