When a person or animal dies, their body starts to break down or decompose. This happens because the body no longer has the energy or ability to keep things working correctly.
First, little bugs called bacteria and fungi start to eat the body. They can be found everywhere, and they like to eat the things that make up our bodies, like proteins and sugars. They also produce gases and liquids that can make the body smell pretty bad. In some cases, these bugs can help to break down the body quickly, but in other cases, they can actually slow the process down.
As time goes by, bigger bugs and animals start to visit the body. They might be attracted by the smell, or they might be looking for a place to lay their eggs. Insects like flies and beetles will eat the body, but they’ll also lay eggs in it. The eggs hatch into maggots, which are little wormy things that like to eat meat.
Over time, the body will start to dry out and turn into something called adipocere or “grave wax.” This is a grey, waxy material that forms when the body’s fat interacts with the chemicals in the soil around it. This can help to preserve the body and slow down the decomposition process.
Eventually, if the body is left alone, it will become bones. This happens because the bugs and bacteria have eaten everything else, and the only thing left is the hard, mineral part of the bones. Depending on the conditions where the body was left, this process can take anywhere from a few weeks to several years.
Overall, decomposition is a natural process that happens to all living things when they die. Even though it might seem gross, it’s an important part of the Earth’s ecosystem because it helps to recycle materials and make them available for other living things to use.
