Answer 1

Answer: (C)

Parabiosphere

Pedosphere is the outer most layer of earth which exhibit soil formation and consists of minerals, air, water and organic matter. It is the zone of interaction of atmosphere, biosphere, lithosphere and hydrosphere.

All the living organisms of earth and the three abiotic components namely hydrosphere (the water component supporting life), lithosphere (the solid component of earth's crust that supports life) and atmosphere together constitute biosphere. The gaseous envelope of earth that surrounds hydrosphere and lithosphere is called as the atmosphere.

The parts of the biosphere that exhibit all the physiological processes of life constitute biosphere.

On the other hand, the part of the biosphere that is harsh to live and is not inhabited by living organisms is called as parabiosphere. It includes cold ice caps, volcanoes, hot arid deserts etc.

Therefore, the correct answer is option C.
