Answer 1

The biosphere is the part of a planet's outer shell — including air, land, surface rocks and water — within which life occurs, and which biotic processes in turn alter or transform. From the broadest geophysiological 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 (rocks), hydrosphere (water), and atmosphere (air). Our planet Earth is the only place where life is known to exist. This biosphere is generally thought to have evolved, beginning through a process of biogenesis or biopoesis, at least some 3.5 billion years ago.
