Matter consists of chemical elements in pure form and in combinations called compounds. Water is the universal medium for life on Earth, and Carbon in the backbone of life. Carbon enters the bisphere trough the action of plants and it is able to form molecules joining with elements such as Oxygen, Nitogen, Sulphur, and Phosphorus to form organic macromulecules which compose living organisims.
