Answer:
b.hemisphere
Explanation:
The biosphere is the layer and zone in which all life is on the Earth’s surface. It is organized out of living things and elements that provide the life resources.
The hydrosphere is the mass of water that exists on the earth, obviously providing organisms the resource of drinking water necessary for survival.
The lithosphere is the earth's surface of the planet, the one on which we live. As such, it provides us a solid surface to make settlements and shelters, as well as to plant the food.
The atmosphere is the layer of gases around the earth. Oxygen which organisms breathe exists in this sphere.
Hemisphere is the only term that does not refer to the factor necessary for the organisms’ survival. It is the term that defines the half of the sphere, usually referring to the part of the planet Erath (like the northern Hemisphere – the half of the planet which is on the north).
