                                Approximately 78% of Earth's atmosphere consists of nitrogen gas ($N_2$), but in this form, it is unusable by most living organisms. The critical process of how do you convert nitrogen to protein requires a series of biological transformations, primarily carried out by microorganisms and plants, which make this essential element available to the food web.
