This presentation explains the principles of the environment and its mainly explain 10 principle of environment simply and effectively

1. WELCOME

2. PRINCIPLES OF
ENVIRONMENT

3. INTRODUCTION
 “Environment” is the surroundings or conditions in
which a person, animal, or plant lives or operates.
 Environment is the sum total of all surroundings of a
living organism, including natural forces and other
living things, which provide conditions for
development and growth
 The mobility of the environment governs some
principles.

4. 1. PRINCIPLE OF DEPENDENCE AND MUTUAL
INFLUENCE
2. PRINCIPLE OF BALANCE
3. PRINCIPLE OF UNITY (ONENESS)
4. PRINCIPLE OF DIVERSITY
5. PRINCIPLE OF ACTIVE TENDENCY (RESISTIVE
NATURE)
6. PRINCIPLE OF CONTINUOUS PRODUCTION
7. PRINCIPLE OF ADAPTATION
8. PRINCIPLE OF ENERGY FLOW
9. PRINCIPLE OF GROWTH
10. PRINCIPLE OF BEHAVIOUR

5. • Every component depend on others
• This mutual relationship is known as
interaction
Eg: Amount of rainfall and growth of
trees in an area
1.PRINCIPLE OF DEPENDENCE
AND MUTUAL INFLUENCE

6. 2. PRINCIPLE OF BALANCE
Due to the interaction among the
components, the environment remains
more or less stable.
The ability of nature to stabilize itself is
known as the ecological balance .
This balance regulated through food
chains and food webs
Eg: The excess CO2 in the atmosphere
converted into carbon is by shell bearing
organisms of the sea.

7. 3. PRINCIPLE OF UNITY (ONENESS)
(“We are all creatures of one family- St. francis Assissi)
 All organisms are made up of same structural and
functional units- the ‘cells’
 Because of same chemical build up, substance
produced by one organism are usually digested and
assimilated by others.
 Substances prepared artificially by man such as
plastics, glass etc.. cannot be accepted or recycled by
other organisms

8. 4. PRINCIPLE OF DIVERSITY
Composed of different elements
The inclusion of different types of people
(as people of different cultures)
Organisms differ in terms of their
morphological, anatomical and
physiological characteristics
This diversity gives stability to the
environment
Eg: removal of one type of trees may not
adversely affect ecological balance

9. 5. PRINCIPLE OF ACTIVE
TENDENCY (RESISTIVE NATURE)
 Organisms can develop resistance against man made
substances, which is termed as active tendency or
resistive tendency of organisms
Eg: mosquitoes becoming resistant to DDT and other
insecticides

10. 6. PRINCIPLE OF CONTINUOUS
PRODUCTION
 We can obtain various useful products from animals
and plants
 Population of these organisms continually change
 nature has its own checks and balances to keep most
population within rather narrow limits
 An understanding of this helps in judicious
management of natural resources

11. 7. PRINCIPLE OF ADAPTATION
Adaptation also called an adaptive trait
It is a trait with a current functional
role in the life history of an organism
that is maintained and evolved by
means of natural selection.

12. 8. PRINCIPLE OF ENERGY FLOW
 Also called the calorific flow
 It refers to the flow of energy through a food
chain.
 In an ecosystem, ecologists seek to quantify
the relative importance of different
component species and feeding relationships
 Primary producers => Secondary Consumers
=> Tertiary Consumers => Decomposers.

13. 9. PRINCIPLE OF GROWTH
Refers to a positive change in size, often
over a period of time.
Growth can occur as a stage of
maturation or a process toward fullness
or fulfilment.
It can also perpetuate endlessly

14. 10. PRINCIPLE OF BEHAVIOUR
Behaviour is the range of actions and
mannerisms made by organisms,
systems, or artificial entities in
conjunction with themselves or their
environment

15. CONCLUSION
 Nature knows best
 All forms of life are important.
 Everything is connected to everything else
 Everything changes
 Everything goes somewhere
 Ours is a finite earth
 Nature is beautiful and we are stewards of God’s
creation
