Question

Write a short note on biosphere write a short note on biosphere​

Answer 1

The zone of contact between land, air and water, where all forms of life, from the microscopic bacteria to huge whales and elephants live, is known as bio­sphere. It is the most unique feature of the planet earth.

Our earth is unique in the solar system because of the biosphere. No other planet has biosphere and therefore, no life exists. Though Mars may have supported life, but there is no evidence.

Answer 2

The biosphere is made up of the parts of Earth where life exists. ... The solid surface layer of the Earth is the lithosphere. The atmosphere is the layer of air that stretches above the lithosphere. The Earth's water—on the surface, in the ground, and in the air—makes up the hydrosphere.
