Lightning breaks (fixes) N2 and sends N to soil Over time N released back in atmosphere. N2 bonds form so Nitrogen Cycle continues Lightning breaks (fixes) N2 and sends N to soil Herbivores consume plants which contains N Animal waste is deposited on soil which is broken down by decomposers and bacteria. N is returned to soil. Bacteria converts N in soil to ammonia (NH4) which is used in plants
