Explanation:

Biosphere, relatively thin life-supporting stratum of Earth's surface, extending from a few kilometres into the atmosphere to the deep-sea vents of the ocean. The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients.

Answer 2

Explanation:

Biosphere is that part of the earth where life exists. The geographical distribution of living organisms reveals that living creatures are found in different sets of environmental conditions

The biosphere is a life supporting layer which surrounds the earth and makes plant and animal life possible without any protective device. The ‘organic world or biosphere is that part of the earth which contains living organisms – the biologically inhabited soil, air and water’.

The biosphere consists of all the living organisms (the biotic compo­nent), energy (the energy component) and physical environment (the abiotic component) and there are continuous interactions between living organisms and physical environment and among the living organisms themselves.
