Phosphorus exists in DNA and RNA, which life relies upon, as well as lipids and ATP. However, phosphorus does not exist in the atmosphere, unlike carbon and nitrogen,  which means we directly rely on the phosphorus cycle being balanced for our health.

Dead organism decompose and release phosphate back into the ground. Some of this phosphate goes back into the rock cycle and becomes part of sedimentary and metamorphic rocks. ]]> 2019-05-09 04:51:00 UTC https://padlet.com/sahmadi22/4cohw5i6tgfw/wish/358330688 sahmadi22 https://padlet.com/sahmadi22/4cohw5i6tgfw/wish/358331304 2019-05-09 04:55:00 UTC https://padlet.com/sahmadi22/4cohw5i6tgfw/wish/358331304
