The interactions of the ecosystems are all part of the biosphere. The organisms in the biosphere interact with each of the other abiotic physical systems, namely the hydrosphere, the atmosphere and the lithosphere. These interactions not only shape the nature of the ecosystems, but also affect the geology and geography of the system.
