Carbon Dating
Of all the elements, carbon is the one that seems most indispensable to life - the one without
which life on any planet is hardest to envisage. This is because of carbon's remarkable capacity for
forming chains and rings and other complex molecular architectures. It enters the food web via
photosynthesis, which is the process whereby green plants take in carbon dioxide molecules from
the atmosphere and use energy from sunlight to combine the carbon atoms with water to make
sugars. All the car...How it works.
