A non-living thing in biology means any form without a life, such as an inanimate body or object. Compared with the entity that has a life, a non-living thing lacks the features that characterize a living thing. For instance, a non-living thing lacks the fundamental unit of life, a living cell that grows, metabolizes, responds to external stimuli, reproduces, and adapts.
Instead of cells, a non-living thing is made up of elements or compounds that form from chemical reactions. Examples of non-living things are rocks, water, and air.
