This impossible situation is maintained by recycling, by using and reusing the same basic ingredients m dif ferent forms. The earth has a fixed quota of about 92 chemical elements. But those assorted atoms are kept extremely busy. For they are the basic building blocks available to construct all the earth s count'ess solids, liquids and gases The system must woik without wasting these basic materials fourths of the air and the oxygen that makes up about one fourth. Each day. a certain quota starts a tvcle of duties or. the earth Each da the same quota completes a cycle and u turns to the an I.xcs Chemical Reactions Other Stages Involved The mtiogen and owgcn cycles are noccssaiy to support all the life pioc esses ef plants and animals. However, both operations begin with the plant wnild. When plants use caibon dioxide to make their food, Us molecules aic broken apart and some of its oxygen atoms retui n to the am. Nature does this by using chemical reactions. Atoms are united m molecule packages to form compounds of different substances. When their wmrk is done, molecules are broken apart and the onginnl atoms reused to construct other use- Other complex stages may be involved. But as a rule, the oxygen cycle is less complex than the nitrogen cycle. This is because plants cannot use nitrogen in its basic foi m, and its compounds are built into materials that take a long time to break apart. ful compounds.
