Humans use nitrogen in the form of proteins. Bacteria found in soil convert atmospheric nitrogen into nitrates that plants use to produce proteins.
For humans to be able to use nitrogen it must be converted from N2 (g) to ammonium (NH4^+), nitrate (NO3^-), or organic nitrogen. Nitrogen is the majority of the air we breath but it is relatively inert due to the triple bond between N atoms.
Humans impact the nitrogen cycle by making fertilizers and burning fossil fuels, which alter the amount of fixed nitrogen our ecosystems.
Humans contribute to the disruption of the nitrogen cycle through activities like industrial nitrogen fixation, excessive fertilizer use, and deforestation, which release excess nitrogen into the environment. This can lead to issues like water pollution, soil degradation, greenhouse gas emissions, and ecosystem imbalances.
Humans return nitrogen to the soil primarily by using fertilizers containing nitrogen compounds, such as ammonium nitrate or urea. They can also crop rotation, which involves planting leguminous plants that can fix nitrogen back into the soil or by incorporating nitrogen-rich organic matter like compost and manure.
Before humans the main path is from Nitrogen fixing bacteria found in the roots of many plants and from lightning creating nitrogen oxides that are then washed down with the rain. In modern times more than half the nitrogen fixed is from the application of artificial fertiisers and from air polution.
Nitrogen gas (N2) in our atmosphere is an example of a form of nitrogen that humans cannot directly use. Additionally, nitrate (NO3-) in soils is not directly usable by humans and must first be converted by plants into a more bioavailable form of nitrogen.
Through manufacture and use of fertilizers.

Yes, humans do use nitrogen gas for various applications such as in food packaging, semiconductor manufacturing, and as a coolant in some industries. However, we do not breathe nitrogen gas as it does not play a direct role in sustaining human life.
Humans add nitrogen to the biosphere primarily through the use of synthetic fertilizers in agriculture, which then gets taken up by plants and enters the food chain. Additionally, industrial processes involving nitrogen, such as the production of ammonia, also introduce nitrogen into the environment.
oxygen for humans and carbon dioxide for plants
its denser than oxygen and our bodys werent ment to use it
Air/gas animals and humans breathe in, and a little bit of nitrogen is included in the air it has just breathed in.
Animals use nitrogen to build proteins in their bodies. Nitrogen is a vital component of amino acids, which are the building blocks of proteins essential for growth, maintenance, and repair of tissues in animals.
No, humans do not need to breathe nitrogen for survival. The air we breathe is mostly made up of oxygen, with only a small amount of nitrogen. Our bodies use the oxygen in the air for respiration, not the nitrogen.
