Answer:
The age of material
Step-by-step explanation:
Radiocarbon dating is the method which is used to determine age of object that contains organic material by using properties of radiocarbon (¹⁴C).
The ¹⁴C in form of radioactive carbon dioxide formed in the atmosphere is incorporated into the plants by photosynthesis and also animals acquire ¹⁴C by eating these plants.
When a animal or a plant dies, they stops exchanging the carbon with environment and that point onward, the amount of ¹⁴C present in the body of them, begins to decrease as it undergoes radioactive decay.
Measuring amount of ¹⁴C can be used to calculate when the animal or the plant died. Hence, it is used to determine the age of the material.
