Eventually, the entire ecosystem (community of plants and animals) of the planet, including humans, is filled with a concentration of carbon-14.

As long as an organism is alive, the supply of carbon-14 is replenished.

When carbon-14 falls to Earth, it is absorbed by plants.

These plants are eaten by animals who, in turn, are eaten by even larger animals.
