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 not found everywhere, some areas do not support the conditions required for Biosphere. Hence Organisms are not uniformly distributed throughout the world.

Detailed explanation-3: -The biosphere is the life-supporting stratum of earth’s surface., including the hydrosphere, lithosphere, and atmosphere. It is the place wherein all living organisms interact with the abiolitic components of the ecosystem. The biosphere extends to a height of 20 km from the ocean floor.

Detailed explanation-4: -There are eight major terrestrial biomes: tropical rainforests, savannas, subtropical deserts, chaparral, temperate grasslands, temperate forests, boreal forests, and Arctic tundra.

Detailed explanation-5: -The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients.
