Why nitrogen important for animals and plants

Nitrogen can be returned to the environment when an animal excretes or dies. Nitrogen is found in proteins and Amino acids which are in DNA and are the building blocks of life. Nitrogen is essentially the secret ingredient in the recipe of our existence. Without it, us humans and animals wouldn't be here.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.
