Answer 2

Answer:

Bio means life. The biosphere is the domain of the earth in which life exists. Living organism cannot live deep in the crust of the earth or high up in the atmosphere; very few marine organisms are able to survive in the deepest part of the ocean. Life survives and thrives in the narrow contact zone of the lithosphere, hydrosphere, and atmosphere and it is called the biosphere, so that is the reason why biosphere is considered the domain of life.
