Yes, "bio" refers to biology or living things. In the context of the biosphere, it refers to the area of the earth where all living things exist.

They exist in the air and water, not just where the earth is solid.

You are correct. Living things exist not only on solid land but also in the air and water. The biosphere encompasses the entire sphere of the Earth where life can be found, including the atmosphere, hydrosphere (water bodies), and lithosphere (solid land). It is the zone where organisms interact with their environment and includes various ecosystems such as forests, deserts, oceans, and freshwater bodies.
