Nitrogen Cycle is a biogeochemical process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere. It involves several processes such as nitrogen fixation, nitrification, denitrification, decay and putrefaction.
To be able to use nitrogen, plants convert atmospheric nitrogen to nitrates, nitrites and ammonia compounds by a process called the nitrogen cycle. Animals derive their nitrogen requirements from plants.
The nitrogen cycle is a cyclic process where the nitrogen travels from inorganic form in the atmosphere and to the organic way in the living organisms. The nitrogen cycle contains several steps, such as nitrogen fixation, assimilation, ammonification, nitrification, and denitrification.
Jul 3, 2023 · Nitrogen Cycle. Nitrogen is required by both, plants and animals for their growth and development. It is an essential component of proteins which make up the bodies of plants and animals. It is also present in chlorophyll, nucleic acid and vitamins.
The Nitrogen Cycle is an earth’s natural process which converts inert nitrogen in the atmosphere towards a more useful form for living organisms.” Nitrogen is an important nutrient plant nutrient. However, plants and animals cannot directly use the plentiful nitrogen in the atmosphere.
Jun 9, 2016 · In general, the nitrogen cycle has five steps: 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)
