All living things contain a small amount of carbon- 14, which is radioactive and decays. The half-life of carbon-14 is 5,600 years. During the lifetime of an organism, the carbon- 14 is replenished, but after its death the carbon- 14 begins to disappear. By measuring the amount left, the age of the organism can be determined with surprising accuracy. The line graph below shows the fraction of carbon- 14 remaining after the death of an organism. Use the line graph to complete the table.
