The ancient Greek word bios (βίος) pertains to the physical, earthly life of a person, animal or plant and commonly focuses on the duration, manner, or means of existence. It signifies biological life, as opposed to spiritual, eternal life.
Now
Bios refers to Earth's living components - all organic life, ecosystems and biological processes. It is commonly used in scientific, ecological and sustainability contexts to distinguish the living environment from the non-living (abiotic) environment.
