What sphere do earthworms belong to what does soil belong to?

Earthworms belong to the biOSphere, as they are living organisms that contribute to ecosystems and interact with other life forms. Soil, on the other hand, is part of the lithosphere, which encompasses the Earth's solid outer layer, including rocks and minerals. Together, earthworms and soil play a crucial role in nutrient cycling and supporting plant life within the biOSphere.
