Explanation: 

Detailed explanation-1: -Virus-a small nonliving particle that invades and then multiplies inside a living cell. Biologists consider viruses to be nonliving because viruses are not cells. Viruses do not use energy to grow or respond to their surroundings. Viruses can multiply.

Detailed explanation-2: -A virus is a tiny, nonliving particle that enters and then reproduces inside a living cell.

Detailed explanation-3: -Once inside a host, viruses invade the organism’s cells and “hijack” them, causing them to stop performing their normal functions and to start making more copies of the virus. Viruses are really, really, small (even 100x smaller than bacteria!) pathogens that can only replicate within a living organism, called a host.
