Detailed explanation-1: -The biosphere is made up of the parts of Earth where life exists. The biosphere extends from the deepest root systems of trees, to the dark environment of ocean trenches, to lush rainforests and high mountaintops. Scientists describe Earth in terms of spheres. The solid surface layer of Earth is the lithosphere.
Detailed explanation-2: -The biosphere includes all life on our planet. It is not only all the things that are living, but also the remains of organisms that have died and not yet decomposed. It also includes the regions of the other parts of the Earth system (atmosphere, hydrosphere, geosphere) occupied by living organisms.
Detailed explanation-3: -The biosphere is the thin life-supporting stratum of Earth’s surface, extending from a few kilometres into the atmosphere to the deep-sea vents of the ocean. It is composed of living organisms and nonliving factors from which the organisms derive energy and nutrients.
