$\huge\mathbb\green{BIOSPHERE:}$

Biosphere basically means regions of Earth's crust and atmosphere occupied by the living organism.

___________________________

Biosphere can be further be divided into three physical divisions i.e., lithosphere (land), hydrosphere (water), and atmosphere (air).

⬇️⬇️⬇️

$\large\red{Lithosphere:}$

=> The outer solid crust of Earth which we call land is known as lithosphere.

=> Its upper weathered part forms the soil.

$\large\red{Hydrosphere:}$

=> The water component of Earth is called hydrosphere.

=> 75% of the Earth's surface covered with water in the form of seas, rivers, lakes, ponds, etc.

$\large\red{Atmosphere:}$

=> The blanket of air that covers whole Earth is known as atmosphere.

$\huge\bold\pink{Extras:}$

• Biosphere has two types of components, biotic and abiotic.

• Living beings mainly are the biotic components of the biosphere.

• Air, water, soil, etc. forms the non-living or abiotic component of the biosphere.

• Both the types of these provide resources for the basic needs of life forms.

• However, the main energy for supporting all these life forms is basically from the sun.

• Sun's energy is used in the synthesis of food for all the living beings present on our planet i.e., Earth.
