How do humans and animals get nitrogen?
Nitrogen starts in soil and becomes useful nitrogen for plants and it gets passed on to animals. Decomposers would eat nitrogen-rich dead organisms and some of the nitrogen goes back into the soil.
What is a misconception about air?
A common misconception is that air is mostly oxygen. 78% of air is nitrogen and only 20% is oxygen. Nitrogen is inert and flows in and out of our lungs untouched, but we require oxygen to live, so it gets absorbed.
How the nitrogen is separated from air. what is the needed temperature for that?
You need to get the air liquid and then evaporate it - oxygen evaporates more easily than nitrogen. At normal pressure, air gets liquefied at about 78 kelvin (-195 degrees Celsius).
Does nitrogen contain air?
Nitrogen doesn't contain air, but the air contains Nitrogen.
How nitrogen enters the atmosphere?
Typically, atmospheric nitrogen gets into the soil by nitrogen-fixing bacteria that are symbiotic with such plants as clover, soybeans and alfalfa. Bacteria in the plant extract nitrogen from the air, and when the plants die, the nitrogen remains in the soil as the plant decays.

Is nitrogen in air?
Yes. About 75% of air is Nitrogen.
What percentage of nitrogen is their in your air?
About 78% of air is Nitrogen.
How much nitrogen is there in the air?
There is about 78.09% of nitrogen in the air.
What is the percent if the air is nitrogen?
Our air is about 79% Nitrogen.
What is the main way nitrogen gets from the atmosphere to earth?
lightening bolts ionized air molecules and create nitrogen compounds which are then carried by rain water down to the earth. Nitrogen-fixing bacteria would be responsible for the greatest bulk of fixed nitrogen.
What is the main way that nitrogen gas leaves the soil and gets into the air?
The main way nitrogen gas leaves the soil and gets into the air is through a process called denitrification. Denitrifying bacteria convert nitrate, a form of nitrogen found in the soil, back into nitrogen gas which is then released into the atmosphere. This occurs in oxygen-poor environments such as water-logged soils and wetlands.
