Describe the Steps of the Nitrogen Cycle
Nitrogen Fixation Ammonification Decay Nitrification De-nitrification. Inorganic nitrogen is uptaken by the roots of plants and becomes part of the food chain. Nitrogen Cycle Components Process Role The Cyclic Path Nitrogen fixation N2 to NH3 NH4 or NO3- Nitrification NH3 to NO3- Assimilation Incorporation of NH3 and NO3- into biological tissues Ammonification organic nitrogen compounds to NH3 Denitrification NO3- to N2 Similarly how would you describe the nitrogen cycle. . Use Figure 4213 to describe the carbon cycle. Biological nitrogen fixation is the major source of fixed nitrogen up-to 140 700 mgm 2 year as against 35 mgm 2 year by electrical discharge and photochemical fixation. The nitrogen cycle involves three major steps. This reaction involves the addition of oxygen to ammonia giving rise to hydroxylamine NH 2 OH which is further oxidized to nitrite. Nitrogen Cycle Steps Well discuss each part of the process belo...
