The biological aspects of the cycle are that inorganic phosphates are taken in by plants from the soil. The animals will eat the plants and then they are put back into the earth when that animal dies. The geological aspects of the cycle in ocean and water areas the phosphate is incorporated into and form rocks, and through erosion they are returned to the soil, lakes, rivers, and streams. The chemical aspects are that some rocks that contain phosphorus are mined and then turned into fertilizers, which are also put back into the ground to start the cycle over again. Gardner grew up in no spectacular manner. He excelled at football and went to college on a scholarship. He stayed in school and went to law school and later went to become a public defender. Unbeknownst to Gardner, when the alien Green Lantern Abin Sur crashed on Earth and sought a replacement, the ring found two appropriate candidates: Gardner and test pilot Hal Jordan. Because Jordan was closer, he was chosen to be the successor to Abin Sur and receive his ring and become the next Green Lantern.
