what are the IMPORTANCE of NITROGEN CYCLE for HUMAN?

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.
