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 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.
Detailed explanation-3: -Earth’s living things make up the biosphere. The living portion of the Earth interacts with all the other spheres. Living things need water (hydrosphere), chemicals from the atmosphere, and nutrients gained by eating things in the biosphere.
Detailed explanation-4: -The term “biosphere” was coined by geologist Eduard Suess in 1875, which he defined as the place on Earth’s surface where life dwells.
