Biology-Online.org defines a non-living object as being "dead or not living" or an "inanimate body or object." Rocks, firewood and cars are a few examples of non-living objects.
As Biology-Online points out, non-living objects lack all characteristics of life and thus cannot grow, move or reproduce. They may change over time, such a when wood burns and water erodes rock, but they do not adapt to a changing environment. The term non-living object can refer not only to "things" like tables and TVs, but also to beings which were once alive and have died, such as plants, animals and people.
