The solid part of the ecosystem is referred to as the lithosphere. The lithosphere includes the Earth's crust and the uppermost part of the mantle, and it is the layer that supports all life on Earth. It is made up of rocks, minerals, and soils that provide the foundation for all terrestrial life. The lithosphere interacts with the other components of the ecosystem, such as the atmosphere, hydrosphere, and biosphere, through various physical, chemical, and biological processes. Together, these components make up the Earth's ecosystem, which sustains life on our planet.
