Living organisms can incorporate various forms of nitrogen into their metabolism. While most organisms cannot directly use nitrogen gas (N2) due to its inertness, they can incorporate other forms of nitrogen such as ammonia (NH3), nitrites (NO2-), and nitrates (NO3-). Some bacteria and archaea can fix atmospheric nitrogen gas into a usable form through a process called nitrogen fixation. However, when answering a question that requires you to select one, it's important to choose the most generally applicable form of nitrogen.
nitrates
Nitrates (NO3-) are commonly taken up by plants and other organisms and incorporated into their metabolism, as they are a more oxidized and readily available form of nitrogen for many organisms.
