First, certain plants are able to absorb or "fix" nitrogen through their root systems. These plants are called legumes and include clover and peas. Legumes are distinguished by nitrogen-fixing bacteria that live inside their root noles. These bacteria change the N2 form of atmospheric nitrogen into nitrate, NO3 : N2 + 3O2 ---> 2NO3In the nitrate, form the legumes, as well as other plants, can utilize the needed nitrogen.Through a diet that includes either these plants directly or the procts from grazing animals we make the nitrogen available to our bodies.The se買粉絲nd major way by which nitrogen is transformed into a usable form is by lightning. The great electrical energy of lightning is easily able to 買粉絲nvert N2 to NO3.
