They have the same ratio of carbon-14 to carbon-12 as the atmosphere, and this same ratio is then carried up the food chain all the way to apex predators, like sharks.
They should also understand that the atoms of any element are alike but are different from atoms of other elements.
Atoms may stick together in well-defined molecules or they could be packed together in large arrays.

To understand radiocarbon dating, you first have to understand the word Although an element’s number of protons cannot change, the number of neutrons can vary slightly from each atom.
