What is nitrogen fixation? Mention 3 ways of nitrogen fixation & chemical reactions related to this process.
pls ans fast
Kindly refer to the answer given by John for the first two parts of your question, I am providing you the reactions involved in the nitrogen cycle -
The nitrogen present in atmosphere is biologically fixed by the bacteria into ammonia. This ammonia undergo the process of nitrification leading to the formation of nitrates-
The nitrate so formed can be easily absorbed by the plants, and transported to leaves. Animals get their nitrogen by consuming plants.
When plants & animals die, nitrates are reduced back to nitrogen in the atmosphere, this process is known as denitrification & the bacteria which carry out this process are known as denitrifying bacteria for example- Pseudomonas.
@ Others;- Good answers, keep contributing!!
nitrogen fixation is process through which atmospheric nitrogen is fixed into nitrates and nitrites.
three ways of nitrogen fixation are:-
1-by nitrogen fixation bacteria present in root nodules of legume plants(e.g. rhizobium,azotobactor).
2-by lightning in sky under high pressure and temperature.
3-by industrial fixation in industries making fertilizers and pesticides.
