Answer 1

6) No, the Biospherecannot exist in the absence on even any one of the three          spheres or realms. This is because no biotic creature (living organism) can          exist in absence of either atmosphere, lithosphere or hydrosphere. Nothing        will be ablt to survive in the absence of atmoshphere, as air is required by        every living organism for survival. They also need land to live on and water to     drink. Thus, the Biosphere won't exist in the absence of any one of them.

7) Us Human beings are a bit different from the other cratures as we have an         advanced logical and reasoning power. The power to differentiate objects            and understand and develop them makes us very different from the others.
