Illustrate the nitrogen cycle and explain using a flow chart.
Answers
Explanation:
the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition
The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification. The majority of Earth's atmosphere (78%) is atmosphere nitrogen, making it the largest source of nitrogen. However, atmospheric nitrogen has limited availability for biological use, leading to a scarcity of usable nitrogen in many types of ecosystems.
I HOPE IT WILL BE HELPFUL.
Nitrogen Cycle : The complete series of cyclical events by which nitrogen from atmosphere enters into the compositions of organisms and from organisms it is released to the atmoshphere again tp maintain the equilibrium of atmospheric nitrogen is called NITROGEN CYCLE.
Steps : Nitrogen cycle cosnsists of various steps such as - Nitrogen fixation, Ammonification, Nitrification, Denitrification.
Significances :
1] Nitrogen cycle maintains the nitrogen equilibrium in atmosphere.
2] Nitrogen cycle maintains the balance between the gaseous nitrogen and soil nitrates.
3] Nitrogen is an essential component of protein. It is also required for synthesis of nucleic acids like DNA and RNA. So, nitrogen cycle is useful for maintaining the equilibrium of nitrogen.
