Biology for Non-STEM Majors
Nitrogen fixation is the process by which atmospheric nitrogen ($$N_2$$) is converted into a form that living organisms can use, typically ammonia ($$NH_3$$). This crucial biological process occurs mainly through the action of certain bacteria and archaea, allowing nitrogen to enter the food web and ultimately supporting the growth of plants and other organisms. Understanding this process is essential in the context of nutrient cycling and the functioning of terrestrial ecosystems.
