Carbon is a fundamental element in organic compounds, present in all living things. It is also found in the atmosphere as carbon - dioxide, in rocks as carbonates, in soil as organic matter, and in oceans as dissolved carbonates.

Water is not an element and while important, not as integral to the structure of living things and rocks in the same elemental sense as carbon.
