You might remember that it was mentioned earlier that the amount of carbon-14 in living things is the same as the atmosphere.Once they die, they stop taking in carbon-14, and the amount present starts to decrease at a constant half-life rate.However, once the organism dies, the amount of carbon-14 steadily decreases.By measuring the amount of carbon-14 left in the organism, it's possible to work out how old it is.As a member, you'll also get unlimited access to over 70,000 lessons in math, English, science, history, and more.

Anyone can earn credit-by-exam regardless of age or education level.Atmospheric carbon-14 rapidly reacts with oxygen in air to form carbon dioxide and enters the carbon cycle.Plants take in carbon dioxide through photosynthesis and the carbon-14 makes its way up the food chain and into all living organisms.Then the radiocarbon dating measures remaining radioactivity.By knowing how much carbon-14 is left in a sample, the age of the organism and when it died can be worked out.
