Everyone uses nitrogen all day every day. The earth's atmosphere is 78% nitrogen so you are breath it with every breath and it helps the body absorb oxygen and stabilizes your blood. It is also used in tires on airplanes and in airplane struts because it doesn't expand or contract as much as plain air. When it is kept below 370 degrees it will be in liquid form and can be used by doctors to freeze off warts or skin growths. It is used industrially for all manner of things.

∙ 14y agoNitrogen is inaccessible to most living organisms as a gas (N2). Nitrogen gas must first be "fixed" by soil bacteria living in association with the roots of particular plant like legumes, clover, alfalfa, soybeans, peas, peanuts, and beans.
Living on nodules around the roots of legumes, the bacteria chemically combine nitrogen in the air to form nitrates (NO3) and ammonia (NH3) making it available to plants.
This is part of the Nitrogen cycle.
Examples:
Diazotrophs
Cyanobacteria
Azotobacteraceae
Rhizobia
Frankia

Why is the nitrogen cycle needed when approximately 78 percent of the atmosphere is nitrogen gas?
Nitrogen occurs as a diatomic gas in the atmosphere. It is usually not that reactive because two nitrogen atoms are bonded together by triple bonds. Liquid nitrogen has varied uses. For example getting extremely temperatures, magnetic levitation, in the filed of medicine etc.
How much nitrogen gas is in the atmosphere N2?
The Earth's atmosphere is approximately 79% nitrogen.
What is the transfer of nitrogen from the atmosphere to plants and back to the atmosphere or directly into plants again?
Nitrogen cycle
Which planet has is atmosphere mostly made of nitrogen?
Neptune (NovaNet) There's something wrong here. Neptune is mainly a hydrogen atmosphere. Earth is the planet with a mainly nitrogen atmosphere, but the coldest is Neptune.
What two chemical elements make up most of Earth's atmosphere?
99% of the atmosphere is nitrogen (78%) and oxygen (21%).
How is Nitrogen used in the atmosphere?
Nitrogen is used in the atmosphere by.....
How does nitrogen get in the earths atmosphere?
Nitrogen gets into the earth's atmosphere through the nitrogen cycle.
What type of nitrogen is found in the atmosphere?
Nitrogen is found in the atmosphere as diatomic elemental nitrogen, N2.
Does the atmosphere have more nitrogen or oxygen in it?
Nitrogen is more in the atmosphere. Around 78% of the atmosphere is nitrogen gas and 21% is oxygen gas.
