biogeochemicals

"Geo" chemicals exist in the earth when carbon (CO2) nitrogen(N2)from the air is sucked in from the plants roots. When "bio" roots are in organisms it means that a consumer ate the plant with the chemical inside. The chemicals also exist in the air and water because of the cycles. If it weren't for these cycles we wouldn't have oxygen,plants,food, or life of any type.
