Biosphere:
⇒ An Overview
The narrow zone of the earth where the three main components - lithosphere, hydrosphere and atmosphere meet together to sustain life is known as biosphere. It is a combination of both biotic and abiotic factors. All living organisms - the birds, the plants, the microbes etc. live in the biosphere. No organisms can live without any one of them. It is the sphere where life exists.
⇒ Derivation
The word biosphere derives from two Greek words - bios and sphaira that mean life and zone respectively.
⇒ Components
The different components of the biosphere are discussed below:
✳ Atmosphere - The atmosphere refers to the dome of air. The sky, the clouds, the air all fall in the category.
✳ Hydrosphere - The hydrosphere refers to the dome of water. The lakes, the ponds, the seas, the oceans etc. fall in this category.
✳ Lithosphere - The lithosphere refers to the dome of land. It refers to the terrestrial area.
⇒ Why is biosphere important?
No organisms can live without biosphere. Consider the following examples:
A bird
A bird flies in the air. --- Atmosphere
It sits on a tree to rest. --- Lithosphere
It catches fish from ponds. --- Hydrosphere
A fish
A fish lives in water. --- Hydrosphere
It needs air to breathe. --- Atmosphere
It lays its eggs in water that settle on the ground. --- Lithosphere
A cat
A cat lives on land. --- Lithosphere
It needs air to breathe. --- Atmosphere
It drinks water. --- Hydrosphere
In all these examples, we can clearly observe that the participation of all the three components is required for a living organism to live. Hence, biosphere is important.
