The portion of the earth and its environment which can support life is known as Biosphere.

Explanation:

• Biosphere is a little space compared to the other layers of the earth in which living things can survive.
• The earth has many layers in its atmosphere.
• Troposphere, stratosphere,mesosphere,thermosphere and exosphere.
• Troposphere is above the sea level.It is 10 Km from the ground level.
• At the end of troposphere, the stratosphere starts upto 50 Km.
• The infamous ozone layer is found within this stratosphere.
• At the end of stratosphere,the mesosphere is found.
• It is upto 85 Km upwards.
• Most meteors burn up in the mesosphere.
• The layer of very rare air above the mesosphere is called the thermosphere.
• The exosphere is constantly though very gradually "leaking" out of Earth's atmosphere into outer space. There is no clear-cut upper boundary where the exosphere finally fades away into space.
