What happens to atoms when food is being digested

While plants can produce their own energy using the process of photosynthesis, animals (and other organisms that can’t do photosynthesis) must eat to get energy from food molecules. Just like energy can be stored in the chemical bond between the second and third phosphate of an ATP molecule, energy can also be stored in the chemical bonds that make up food molecules. Most of the energy that we use comes from molecules of glucose, a simple sugar.

A) it will stay on the table

Carbon-14 has a half-life of 5,730 years and most igneous rock is older than that.
