What is the importance of Nitrogen in the atmosphere?

Question

I need to know how Nitrogen helps in keeping the ecological balance?

Answer 1

What makes nitrogen so important?
Nitrogen is a big part of Earth’s atmosphere. In fact, nitrogen makes up 78 percent of our air. Nitrogen is extremely important in living things. It forms the building blocks of proteins. We need proteins because they make up our skin and hair. Proteins also help us digest food. We get our nitrogen from plants, and plants get it from bacteria in the soil. Our atmosphere provides life with the nitrogen it needs.

How does nitrogen get to plants and animals from the air?
The nitrogen cycle is one of the important systems for living things. Bacteria take nitrogen out of the air and change it into nutrients in the soil. Those nutrients help plants grow. When animals eat plants, they also eat the nitrogen inside the plants. The animals return nitrogen to the soil through their waste. Plants and animals also return nitrogen into the soil with their bodies when they die. The cycle is completed when other bacteria process the plant and animal material and release nitrogen back into the soil and air.

What is the relationship between nitrogen and pressure?
Nitrogen not only provides valuable nutrients for life, it also serves another very important purpose. There is so much nitrogen in our atmosphere that it adds extra mass to the air. When you add more mass to the atmosphere, it increases the pressure the same way that adding extra air to a bicycle tire increases the pressure inside the tube. Too much or too little pressure can have a serious effect on us if we are unprotected. Deep sea divers, like oil rig workers, experience high amounts of pressure when they are deep in the ocean. The surrounding water squeezes their bodies and they must wear special suits to protect themselves from getting squashed. Astronauts in space must also wear special suits. In space, there is so little pressure around them that the air in their lungs would rush out and their bodies would puff up like a balloon.

although we sometimes say that carbon is the basic building block of life, nitrogen is just as important - it is the atom that forms most of the sticky part of the backbone that makes things work. DNA forms double helices through nitrogen, proteins fold and form enzymes to a great degree because of nitrogen. the source of just about all nitrogen in the biosphere is nitrogen gas from the atmosphere. nitrogen fixation is process of how the nitrogen gas N2 is turned into ammonia and other reduced biological forms of nitrogen it is so difficult to get nitrogen that the only things that can do it are archaebacteria which live deep in the earth, mostly on plant roots where there is no oxygen.

Answer 5

Without the 78% of nitrogen in the atmosphere the 20% oxygen would be increased to about 96%. Oxygen is extremely reactive, having the second highest electronegativity of all the elements (fluorine has the highest electronegativity). Without nitrogen, carbon would spontaneously ignite and life would not be possible, except under the oceans. Of course, when all carbon and other elements had combined with oxygen then carbon dioxide you fill the atmosphere, and life couldn't exist.
