Carbonic Acid - One of the six molecules that dominate life. When some carbon dioxide dissolves in water, carbonic acid forms. The acid dissociates to form hydrogen ions that bond with water to form hydronium cations and bicarbonate anions. Lichens are organisms made up of fungi and algae connected in highly ordered ways that ensure benefits to both organisms. As they grow and respire they give off carbon dioxide and water. As some of the carbon dioxide dissolves in water, carbonic acid forms. The acid decomposes rocks very slowly and essential elements are released for growth of trees and many other organisms. They do not injure trees.
