Viruses are considered non living since they 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.

Answer:

1-Viruses also lack the properties of living things: They have no energy metabolism, they do not grow, they produce no waste products, and they do not respond to stimuli.

2-They also don't reproduce independently but must replicate by invading living cells.
