What is biosphere? Describe various components of biosphere with suitable examples.

Answer 1

Explanation:

The biosphere is made of three parts, called the lithosphere, atmosphere and hydrosphere. Some portions of each may not support life, however; for example, the upper regions of the atmosphere do not support life, while the lower regions do.

Biosphere means all that is about life. It includes all the plants, animal and even the microorganisms. It also extends to the above areas of the atmosphere where birds and insects live. So, it includes any type of place where life might exist. In a broader view, it consists of the lithosphere, hydrosphere, and atmosphere. It is a part of the global ecological system that integrates all the living beings and their relationship. So it is said that life itself constitutes a separate sphere called the biosphere.
