Some occupations and careers that use nitrogen include food packaging (to extend shelf life), medical field (cryotherapy and preserving biological samples), manufacturing (as a coolant and purge gas), and the aerospace industry (for pressurizing fuel tanks and as a propellant).
During nitrogen fixation, nitrogen gas is converted into ammonia or other forms of usable nitrogen by nitrogen-fixing bacteria. This process is important because plants and other organisms cannot use atmospheric nitrogen directly in this form.
the answer is "nitrogen fixation" because nitrogen fixation is The conversion of atmospheric nitrogen into compounds, such as ammonia, by natural agencies or various industrial processes.Read more: nitrogen-fixation
When we breathe in air, about 78% of it is nitrogen. Our bodies do not use this nitrogen, so when we exhale, the nitrogen is released back into the atmosphere unchanged.
Plants obtain nitrogen through a process called nitrogen fixation, where certain bacteria convert atmospheric nitrogen into a form that plants can use, such as ammonia. This can occur naturally in soil or through symbiotic relationships with certain plants like legumes.
An example of the nitrogen cycle is when nitrogen gas in the atmosphere is converted by bacteria into a form that plants can absorb from the soil. Plants then use this nitrogen to grow. When plants and animals die, decomposers break down their organic matter, releasing nitrogen back into the soil for plants to use again.

The concept of careers ranges from descriptions of jobs, occupations, or vocations to the pattern of work and work-related activities that develop through a lifetime.
The occupations that paid the most in the 1930s were professional careers. These included lawyers, some doctors, stock brokers, and other business people.
