Answer:
The three stages of decomposition are livor mortis, algor mortis, and rigor mortis.
The first, livor mortis, means ''discoloration of death''. What this means is that once someone dies, the blood starts draining from the extremities down to the area that's on the ground. For example, a body lying on its back is going to be pale on the chest and face, while dark on the back and buttocks.
The second, algor mortis, means ''coldness of death''. This is where the body starts to cool down in temperature and this stage lasts for a few hours. However, it does not start till 30 minutes to an hour after death.
The third, rigor mortis, means ''stiffness of death''. This is where the body muscles will contract and make a body stiff, which starts a few hours after the death and can continue up to 24 hours.
