nitrogen cycle  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 Nitrogen changes forms throughout the process and from the atmosphere to the soil to organisms and back again There are five stages of the nitrogen cycle

In National 4 Biology discover how atmospheric nitrogen is processed by bacteria, allowing plants and animals to build essential proteins  Nitrogen transforms into several different forms in the 4 steps of the nitrogen cycle

Nitrogen transforms into several different forms in the 4 steps of the nitrogen cycle In an aerobic medium, organic nitrogen matter converts into ammonia salts which in turn convert into nitrites and then into nitrates by
