The layer that houses all living organisms is the

Explanation:
Life resides across the biosphere—the global sum of all ecosystems and the environments where living organisms exist and interact with air, water, and rocks. It isn’t just the air or the water or the solid Earth on its own, but the living part of those systems together. The atmosphere is simply the layer of gases around Earth, the hydrosphere is all the planet’s water, and the geosphere is the solid Earth. None of those alone define where life exists, whereas the biosphere specifically refers to the realm that houses living organisms and their habitats.
