principles of environment

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. PRINCIPLE OF DEPENDENCE AND MUTUAL INFLUENCE PRINCIPLE OF BALANCE PRINCIPLE OF UNITY (ONENESS) PRINCIPLE OF DIVERSITY P rinciple of active tendency (RESISTIVE NATURE) PRINCIPLE OF CONTINUOUS PRODUCTION PRINCIPLE OF ADAPTATION PRINCIPLE OF ENERGY FLOW PRINCIPLE OF GROWTH 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 r efers 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
