Do virus mutations break the laws of thermodynamics?


How does a non-living thing like a virus mutate?

I have heard virologists liken viruses to seeds but seeds have cells, metabolisms, water and other energy stores and active running processes — seeds are alive.

The same way living things mutate.

No, it doesn't violate the second law of thermodynamics, as far as we know, nothing does, that's why it is called a law :). Even if entropy decreases locally (like in a single organism) the process generates more external entropy that causes the total entropy of the universe to increase.

viruses just use the host cell's "metabolism, water and energy stores".

Even if we assume a virus is a non-living thing, they reproduce by taking over a living thing, a cell. Mutations occur when a copy of the virus produced by the cell isn't an exact copy. The copying requires energy provided by the cell, but the errors in the copying require no energy, per se, so the law of thermodynamics is not broken.

No.
