Non-living things are things that are not alive,dead,but not all of them were always dead. Things like sand and glass were never living,but things like paper were once part of a living tree. Even though they are dead and not living anymore,they can perform living characteristics. Eg. A living animal can move, while a non-living car can do the same. But the differences between these two is that an animal can perform all seven characteristics while a car can not.
Living things are alive. They show all the seven characteristics of Living things. Non living things can show one or two of the seven characteristics but they can not show all seven characteristics like all living things. Living things perform movement,respiration,sensitivity,growth,reproduction,excretion and nutrients.
