Describe nitrogen cycle.
Answers
The nitrogen cycle is a repeating cycle of processes during which nitrogen moves through both living and non-living things: the atmosphere, soil, water, plants, animals and bacteria. In order to move through the different parts of the cycle, nitrogen must change forms. In the atmosphere, nitrogen exists as a gas (N2), but in the soils it exists as nitrogen oxide, NO, and nitrogen dioxide, NO2, and when used as a fertilizer, can be found in other forms, such as ammonia, NH3, which can be processed even further into a different fertilizer, ammonium nitrate, or NH4NO3.
There are five stages in the nitrogen cycle, and we will now discuss each of them in turn: fixation or volatilization, mineralization, nitrification, immobilization, and denitrification. In this image, microbes in the soil turn nitrogen gas (N2) into what is called volatile ammonia (NH3), so the fixation process is called volatilization. Leaching is where certain forms of nitrogen (such as nitrate, or NO3) becomes dissolved in water and leaks out of the soil, potentially polluting waterways.

Answer:
some bacteria and blue green algae fix the atmospheric nitrogen by converting it into compounds of Nitrogen. The roots of plants absorb these nitrogen compounds and use them for the synthesis of proteins and other compounds of Nitrogen
