Explanation:
Detailed explanation-1: -Rocks do not reproduce, they do not die, and therefore they were never alive. But the line is not always that clear. Life is the process of self-preservation for living beings and can be recognised by life processes; such as eating, metabolism, secretion, reproduction, growth, heredity etc.
Detailed explanation-2: -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.
