Is Earth an biotic or abiotic component?
The area on or near the surface of earth has been divided into four spheres:
Lithosphere containing rocks- abiotic component.
Hydrosphere is composed of all of the water on the earth- abiotic component.
Biosphere is composed of all living organisms on the earth- biotic component.
Atmosphere is the body of air which surrounds the earth- abiotic component.
So, it is concluded that earth is both biotic as well as abiotic.
