* A rock: Rocks are inorganic, meaning they are not made of living cells. They don't grow, reproduce, or respond to their environment.
* A car: Cars are machines made of metal, plastic, and other non-living materials. They don't have the characteristics of life.
* A virus: While viruses can reproduce, they require a host cell to do so. They lack the ability to carry out basic life processes on their own, and are considered by many to be on the edge of the definition of "living."
* A computer: Computers are complex machines, but they don't have the properties of life, such as metabolism or the ability to evolve.
