Physics/Death and Entrophy

Question
Sir,

I was at a physics lecturer and the Visiting Prof said that death is an increase in Entropy..but death is an end to action. When alive we eat , exercise and emit heat..therefore life should give rise to an increase in Entropy, not the other way round?

Tq

Answer
In general, when you look at a whole system, any process increases entropy.  Yes, if you look at living things, they also increase entropy by processing food into energy.  If you look at an organism dying, as it decays the entropy of the system will also increase.

Expertise

I can answer most basic physics questions, physics questions about science fiction and everyday observations of physics, etc. I'm also usually good for science fair advice (I'm the regional science fair director). I do not answer homework problems. I will occasionally point out where a homework solution went wrong, though. I'm usually good at explaining odd observations that seem counterintuitive, energy science, nuclear physics, nuclear astrophysics, and alternative theories of physics are my specialties.

Experience

I was a physics professor at the University of Texas of the Permian Basin, research in nuclear technology and nuclear astrophysics. My travelling science show saw over 20,000 students of all ages. I taught physics, nuclear chemistry, radiation safety, vacuum technology, and answer tons of questions as I tour schools encouraging students to consider careers in science. I moved on to a non-academic job with more research just recently.

Education/Credentials
Ph. D. from Duke University in physics, research in nuclear astrophysics reactions, gamma-ray astronomy technology, and advanced nuclear reactors.
