krebs cycle Key points · In the atmosphere, energy from lightning helps recombine the atoms in nitrogen gas and oxygen gas , forming nitrate  Nitrogen exists in the atmosphere as N 2 ‍ gas In nitrogen fixation, bacteria convert N 2 ‍ into ammonia, a form of nitrogen usable by plants  1 Nitrogen-fixing microbes like bacteria and blue-green algae convert nitrogen into inorganic nitrogen compounds This is called nitrogen

ไมเคิล แจ็คสัน 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
