Question

Why are viruses nonliving

Answer 1

virus isn't considered living because it doesn't need to consume energy to survive, nor is it able to regulate its own temperature.

Answer 2

Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
