Nitrogen Cycle Overview, Steps & Facts - Lesson -

nitrogen cycle  The cycle contains several steps, including nitrogen fixation, assimilation, ammonification, nitrification, and denitrification Nitrogen-fixing The biological nitrogen cycle mainly consists of internal interactions within the reactive nitrogen pool and in- and out-flow between reactive

Nitrogen gas consists of two nitrogen atoms bonded together The process of converting nitrogen gas to ammonia is called nitrogen fixation  All of the nitrogen that is fixed out of the atmosphere goes into plants and then possibly into animals and then as those animals and plants die
