Steps Involved In Nitrogen Cycle: 1.Nitrogen Fixation: Nitrogen Is Available In Abundance In Atmosphere But Plants Can't Take It Directly.Nitrogen Is Converted Into Nitrogenous Compounds Like Nitrates And Nitrites By Biological Fixation ,Industrial Fixation, Lightning. NCERT Solutions Class 8 Science; Nitrogen fixation. Nitrogen Cycle Definition: The nitrogen cycle can be defined as one of the biogeochemical cycles that converts the unusable inert nitrogen existing in the atmosphere into a more usable form of nitrogen for living organisms. It is very very useful. Which step in the nitrogen cycle would you say is the most important? 4)When plants and animals die,the complex nitrogen compounds present in their dead bodies are decomposed and converted into simple compounds of nitrogen by certain bacteria and fungi present in the soil.All the simple compounds of nitrogen formed in this way go into the soil.The compounds of nitrogen which were taken by the plants from the soil during their growth are returned to the soil.These nitrogen compounds are again absorbed by the new plants for their growth and this part of nitrogen cycle is repeated endlessly. Although 78 percent of the atmosphere is nitrogen gas, this gas is unusable by most organisms until it is made available by a series of microbial transformations.
