Life is a biological concept regarding the characteristics, state, or mode that separates a living thing from dead matter.The word itself may refer to a living being or ongoing processes of which living things are a part of. It may also refer to the period during which something is functional (as between birth and death), the condition of an entity that has been born but yet has to die or that which makes a living thing alive.
