5. COMPONENTS OF
ENVIRONMENT
I. Abiotic components
II. Biotic components
III.Biophysical components
IV.Energy components

6. I. ABIOTIC COMPONENTS :-
• The components which surround us but these are non
living .
• Abiotic components are non living chemical and physical
factors in the environment .
• Common abiotic components :-
 Atmosphere
Water
Air and wind
Temperature and sunlight
Chemical elements

7. II . BIOTIC COMPONENTS :-
• Components which surround us but includes living
components .
• Biotic components include :-
a. producers ( autotrophs )
they transfer light , water , carbon dioxide in to energy .
For example ; plants
b . Consumers ( heterotrophs )
they depend upon the producers for food . For example ; animals
c . Decomposers ( detritivores )
they break down chemicals from producers and consumers in to
simpler from which can be reused . For example ; micro – organisms( fungi

8. III . BIOPHYSICAL COMPONENTS :-
• Living and non living components both are when combined
they form biophysical components .
• It includes all the factors that have an influence on the
survival ,development and evolution of organisms . For
examples these components form
A. Marine environment
it is the habitat of 230000 known species of animals and aquatic plants .
B. Atmospheric environment
they transfer light , water , carbon dioxide in to energy . For example ; plants
.
C. Terrestrial environment
it includes all the plants and animals grow up and develop on the surface of
earth . For example ; human , animals ,plants , crops etc .

9. IV . ENERGY COMPONENTS :-
•It includes solar energy , geo
chemical energy , thermo
electrical energy ,nuclear energy
etc .

10. TYPES OF ENVIRONMENT :-
Natural environment :-
The components of
natural environment
are air , water , soil ,
land , readiations ,
forests ,wildlife ,
flora and fauna etc .
Manmade environment :-
It include
transportation ,
housing ,agricultural
and livestock farms
,aquatic farms
,industries ,dams
