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: -Biosphere is the sum of all and hence regarded as the largest ecosystem of the earth. Biosphere is the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms.

Detailed explanation-4: -Biosphere is called the largest ecological system because it will contain all types of ecosystem and surrounded by the atmosphere to balance the life on the earth.
