Hello Everyone! In is video we take a much deeper look at e nitrogen cycle. We not only look at e basics, but talk about why e nitrogen cycle occurs. Nitrogen Cycle Definition Nitrogen Cycle is a biogeochemical process which transforms e inert nitrogen present in e atmosphere to a more usable form for living organisms. Fur ermore, nitrogen is a key nutrient element for plants. However, e abundant nitrogen in e atmosphere cannot be used directly by plants or animals. e nitrogen cycle explains e how nitrogen flows between animals, bacteria, plants, e atmosphere, and e soil on ear. e uniqueness of e nitrogen cycle is at nitrogen is e most abundant gas in e ear ’s atmosphere, about 78 of all air, but it can’t be directly utilized by e animals and plants unless it is converted into. 19, · Governments must seize e historic opportunity of e Rio+20 summit to put e world on a new sustainable course, says an expert panel. e nitrogen cycle.
