"Carbon is an essential building block for all living things."
Brief explanation: Carbon is an element that forms the backbone of organic molecules (proteins, carbohydrates, lipids, nucleic acids). It is not a living organism, it is not the same as carbon dioxide (CO2 is just one carbon-containing compound), and atmospheric carbon levels have changed (they've increased in recent centuries).
