The Nitrogen Cycle: Processes, Impact & Needs

A small amount of nitrogen can be fixed when lightning provides the energy needed for N2 to react with oxygen, producing nitrogen oxide, NO, and

Atmospheric nitrogen must undergo an important process called fixation to make it available for plants to use Nitrogen transforms through

carbon cycle Ammonification is the process of converting organic nitrogen compounds, such as proteins, into ammonia through the action of decomposers, such as bacteria

krebs cycle Certain types of bacteria are able to use the free nitrogen in the air to make nitrogen compounds through a process called nitrogen fixation
