Question

About 80% of the air in our atmosphere is made of nitrogen. All living things need nitrogen; it is a key element in DNA, RNA, and proteins. Your body gets the nitrogen it needs from food. But how does the nitrogen get from the air into the food that we eat? In order for plants and animals to be able to use nitrogen, N2 gas must first be converted to more a chemically available form. Review the picture of the nitrogen cycle. In order for plants and animals to be able to use nitrogen, N2 gas must first be converted to more a chemically available form.
