Question

If a living thing dies then what happens of the atoms inside the body

Open in App
Solution

Generally, atoms are not considered to be alive, even if they are part of a living thing.

So, there is no difference between a hydrogen atom which is part of a water molecule, which is just one of the billions of water molecules in the glass of water I’m drinking, and a hydrogen atom which is part of a protein which is just one of the billions of proteins that make up the muscles in my hand that I use to raise the glass of water to my mouth.

And when I ingest the water, and it is being used by the biochemical machine that is my body, a hydrogen atom from a ‘dead’ water molecule might become part of my living body. On the same account, living creatures are constantly shedding molecules, which are made up of atoms, into their environment. The most notable example is of course carbon dioxide, which is made in almost all living creatures.

As the saying goes: “We are all made of stardust”.
