How were you able to determine if something was living, once living, or never living (non-living)?
snow_lady [41]

Answer:

Must have lived before.

Explanation:

For an organism to be classified as once living, an object must have been part of a living organism or is now dead. When a flower is plucked from a plant it is hard to distinguish between when it is considered alive and when it is now considered once living. An example of a nonliving object is an apple or a dead leaf.Apr 22, 2013
