Detailed explanation-1: -The biosphere is made up of the parts of Earth where life exists-all ecosystems. The biosphere extends from the deepest root systems of trees, to the dark environments of ocean trenches, to lush rain forests, high mountaintops, and transition zones like this one, where ocean and terrestrial ecosystems meet.
Detailed explanation-2: -The biosphere is the narrow zone of contact between land, water, and air where life exists. The biosphere is divided into the plant kingdom and the animal kingdom.
