Explain the steps of Nitrogen Cycle with diagram
Answers
1...nitrogen fixation -- a) conversion of atmospheric nitrogen into nitrogen compounds (ammonia , nitrites and nitrates ) why nitrogen fixing bacteria is called biological nitrogen fixation
b) the process in which nitrogen is converted into nitrogen oxide (NO2,NO3) buy natural ionizing radiations and electrical energy of lightning is called atmospheric nitrogen fixation. this nitrogen oxide are brought down by rain and is used by plants.
2...nitrogen assimilation -- a) it occurs only in plants
it is a process of changing inorganic nitrogen compounds into organic compounds
B) plants are eaten by herbivorous, these herbivorous are eaten by carnivorous, which make their own body protein
3...ammonification -- a)the process in which nitrogenous waste are decomposed by bacteria into ammonium compounds scholar modification
4...nitrification -- the process of nitrate formation by the action of nitrifying bacteria is called nitrification.
5...denitrification-- the conversion of ammonium compounds, nitrites and nitrates by certain bacteria into molecular nitrogen, which escape into atmosphere.
