The biosphere is the part of Earth inhabited by life forms. It includes all living and non-living components interacting as a complex system. The biosphere contains the biotic elements like plants, animals and microorganisms, as well as abiotic elements like air, water and soil. Plants are primary producers that use photosynthesis to convert sunlight into food, while animals and microbes consume other organisms for sustenance and play important roles in decomposition.

2. Earth has 4 major connected systems
a. Biosphere- The biosphere is the part of the
Earth that is inhabited by life
b. Hydrosphere- It contains all of Earth’s water,
ice, water vapor
c. Atmosphere- The air
blanketing Earth’s solid
and liquid surface
d. Lithosphere- It is the
solid & outer part of the
earth. Ex. ( Highland,
rocks, sea floor, and
everything below Earth’s
surface)

3. The Biosphere
1. Life in the Earth System
Biosphere- part of Earth where life
exists & Includes all living and non-living parts.
Ex. Tundras
Deserts
Tropical rain forest
Oceans
Deserts
Tundras

4. Biota-All the plants and Animal life of a specific
region at a specific time.

5. Biotic and Abiotic :
1. Biotic – It is
define as anything
relating to living
organisms. Ex.
plants ,animals &
bacteria.
2. Abiotic – It is non
living components in
ecosystem.
Ex. Soil , water &
atmosphere

6. 1. Weather- day to day conditions ,including temp,
atmospheric pressure, wind & humidity.
2. Climate- long term pattern of weather conditions
in a particular area.

7. 2. Climate- long term pattern of weather conditions

8. Biotic components :
As per biotic components , they includes
plant, animal & micro organisim . These
are also the builder of food chain of
ecosystem.

9. PLANTS :
Plants are the primary producer , because they produce food through
photosynthesis .
They also known as autotrophs.

Autotrophs : Plant produce their own food
Heterotrophs : They can not produce there own food & depends on
other organism .
Photosynthesis : It is the process in which plant convert light energy
to chemical energy.

10. Animals :-
These are the consumer & also known as heterotrophs ,
because they can not produce their own food , depends on
another source like plants & other small animals.
Micro-organism :-
It is the major part of the ecosystem.
They decomposed waste or dead material .
Ex. Fungi ,bacteria, viruses, etc…….
