उत्तर
- Carbon consumption of animals and plants stops after death and only the decaying processes of C-14 take place continuously.
- The ratio of C-14 to C-12 changes constantly with time as C-12 is nonradioactive in dead plants and animals.
- The time passed since the death of a plant or animal can be calculated by carbon dating i.e. by measuring the radioactivity of C-14 and the ratio of C-14 to C-12 present in the remains of the dead organism.
