I'm not so sure.... but I can guess! I think it is the troposphere, thermosphere, and then the exosphere. The order is from the closest to the earth to the farthest from the earth.

The biosphere is made up of three layers: the atmosphere, hydrosphere, and lithosphere. These layers interact significantly, providing the necessary conditions for life on Earth. Each layer contributes uniquely to the ecosystems and overall health of the planet.
