Some measure the decay of isotopes more indirectly.

The carbon 14 present in an organism at the time of its death decays at a steady rate, and so the age of the remains can be calculated from the amount of carbon 14 that is left. The cells of all living things contain carbon atoms that they take in from their environment.

The technique used is called carbon dating, and in this lesson we will learn what this is and how it is used.

Relative dating and radiometric dating are used to determine age of fossils and geologic.

The pathway from the plant to the molecule may have been indirect or lengthy, involving multiple physical, chemical, and biological processes.

Levels of C can represent either mixtures of modern and dead carbon or carbon that was fixed from the atmosphere less than 50,000 years ago.

So by measuring carbon 14 levels in an organism that died long ago, researchers can figure out when it died.

The procedure of radiocarbon dating can be used for remains that are up to 50,000 years old.

Along with hydrogen, nitrogen, oxygen, phosphorus, and sulfur, carbon is a building block of biochemical molecules ranging from fats, proteins, and carbohydrates to active substances such as hormones.

All carbon atoms have a nucleus containing six protons.

In living organisms, which are always taking in carbon, the levels of carbon 14 likewise stay constant.

But in a dead organism, no new carbon is coming in, and its carbon 14 gradually begins to decay.
