air exists freely in the atmosphere as nature ,this air is said to occupies the lower part of the atmosphere ,and it is a composition of gasses in different degrees .the gases are in molecular form .
composition of air simply means the gas molecules that constitute the air .the most common gases here include nitrogen at 79% .this nitrogen is usually in inactive form and must be converted by plans to make food
oxygen is yet another gas that constitutes what we call air ,oxygen is at 21% .this is the gas that we breath .carbon dioxide is at 0.04%
