What is Biosphere?
Biosphere is the part of the earth’s crust water and atmosphere where plants and animals can subsist. Our biosphere is the global sum of all ecosystems. It can also be called the zone of life on Earth. From the broadest bio-physiological point of view, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, hydrosphere and atmosphere.
