oxygen for humans and carbon dioxide for plants
Then Nitrogen you inhale has no use. But nitrogen, from other sources, such as food, helps sperm production.
No. Or else you die.
The atmospheric nitrogen. This is a diatomic and triple bonded form of nitrogen that can not be metabolized by organisms other than some bacteria which convert it into usable form for plants.
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.
No. They can not use nitrogen gas because the triple bonds of nitrogen can only be broken down for use in living things, plants, by the symbiotic bacteria in the root nodes. Then in other forms nitrogen is taken up into the plant and from there to other trophic levels.
You should not use cortizone cream for something else other that what it is meant for. This is because it has an active steroid ingredient and may cause side-effects.
Since the air around you is about 78% nitrogen gas, you might think it would be easy for organisms to retrieve nitrogen easily. However, most organisms cannot use nitrogen gas. Nitrogen gas is called "free" nitrogen because it's not combined with other atoms. Most organisms can use nitrogen only when it has been combined with other elements to form nitrogen-containing compounds. So, is that the answer you were looking for (possibly for homework)?
An organism that breathes a substance other than oxygen is known as an anaerobe. Anaerobes do not require oxygen for respiration and can use other substances such as sulfur or nitrogen compounds.
you can use it to buy things on the Argos website or in the Argos shop
One example is someone at the top level of management.
Nitrogen fixation
Most of the nitrogen that bacteria use comes from the atmosphere in the form of nitrogen gas (N2). Some bacteria, known as nitrogen-fixing bacteria, have the ability to convert atmospheric nitrogen into a form that can be used by other organisms, such as ammonia or nitrate.
