What is Nitrogen Cycle? describe nitrogen cycle?
Answers
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.
Nitrogen Cycle
Explanation:
Nitrogen cycle is the movement of nitrogen through the living and nonliving parts of the environment.
- Nitrogen gas, or "free" nitrogen, it cannot be used by the most organisms.
- Nitrogen fixation is a process by which bacteria convert nitrogen gas into a usable form.
But the most nitrogen fixation is performed by a certain type of bacteria that grows on the roots of some plants.
Plants absorb nitrogen compounds through their roots. Animals get nitrogen by eating plants and other animals.
Decomposers return nitrogen to the soil. Nitrogen eventually breaks down completely.
Free nitrogen is returned to the air. The nitrogen cycle begins again.
When crops are harvested, little nitrogen is returned to the soil. Fertilizers and nitrogen-fixing crops can be used to replace nitrogen in the soil.
