characteristics of living which a non-living doesnt posses are as follows:-

1) Reproduction:- It is the capability to reproduce itself for the continuation of its kinds. (it is the main characteristic of a living thing)

2) grwoth/life cycle :- every living thing has its life cycle. They are are born, get matured, reproduced and death. So once it is born it will die unlike non-living.

3) Energy source :- All living thing requries energy for their vital fucntion. they need to be feed so they they can grow and sustain their life

4) adaptation and reaction :- all living thing will try to adapt in a particular condition so that they can continue their existance. They react to each and every reaction given to them
