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.
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.
What is the percent if the air is nitrogen?
Our air is about 79% Nitrogen.
Does nitrogen contain air?
Nitrogen doesn't contain air, but the air contains Nitrogen.
How atmospheric nitrogen enters the soil?
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.
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?
Denitrification by different types of bacteria of some nitrogen compounds (nitrates, ammonia, nitrites) lead to nitrogen gas which is released in the atosphere.
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.
Where does nitrogen from?
nitrogen come from the ground when it gets in the roots
How the nitrogen is separated from air. what is the needed temperature for that?
Nitrogen can be separated from air through a process called fractional distillation, where air is cooled to extremely low temperatures (-196°C) to turn it into a liquid. The different components of air, including nitrogen, oxygen, and other gases, can then be separated based on their boiling points, with nitrogen being collected as a gas as it evaporates first.
