उत्तर
A rolling stone just rolls down due to gravitational force acting on it. It will stop rolling once it reaches a hurdle or plain ground. Then it cannot roll or move on its own. It needs some external force to cause its movement. Hence it is a non-living object. A living organism would be able to move by itself using its own energy, without depending on external force.
