nitrogen fixation
We get nitrogen in a usable form from our food.
Nothing. Nitrogen is an element, the simplest form of matter.However, you may be thinking of what causes soil ammonium to be nitrified into the nitrate form usable by plants. This is most commonly done by nitrifying bacteria such as Nitrosomonas and Nitrobacter. See the related link below for more information on this process.
...Dear lord. Okay. Nitrogen (dinitrogen - N2) is the most abundant molecule in our atmosphere. However, since it has a bond order of three and very strong bonds at that, it is generally useless. There are certain organisms, called nitrogen - fixing bacteria, though, that can convert nitrogen to ammonia (NH3). Ammonia is usable by plants, who incorporate it into amino acids, etc. and nitrate (NO3-). When animals eat the plants, they use these prefabricated molecules for themselves. This travels up the food chain. Finally, when an animal dies, bacteria break down the fixed nitrogen back to N2 and the process starts all over again.
The reason nitrogen is abundant in the atmosphere yet limits plant growth is that plants cannot make use of elemental nitrogen. The bond between the nitrogen atoms in elemental nitrogen (which is a diatomic gas) is very strong and not easily broken. Therefore, plants must rely on bacteria in order to fix the nitrogen (convert it into a usable form).

nitrogen fixation
It is called nitrogen fixing.
nitrogen fixation
Converting free nitrogen into a usable form ( a compound) is called nitrogen fixation.

Thyere is a process. We use habor process for that.

Chemical Change
changing atmospheric nitrogen to a usable form
Bacteria performs nitrogen fixation, which involves converting the atmospheric nitrogen (N2) into usable organic nitrates (NO3-). Said bacteria are often referred to as nitrogen fixating bacteria. The process is sometimes called nitrification.Scientists have been able to give plants genes from bacteria to help them do a beeter job. This process is called recombinant DNA technology. Nitrogen fixing bacteria are in root nodules on legumes and maybe some other plant groups.Converts nitrogen in the air to nitrates.
