In this slide there is a complete knowledge of what is extinction and extinct species. This slide will able to show how the species are endangered and extinct.

5. Types of extinction species
Natural extinction
Mass extinction
Planned extinction

6. Natural Extinction& Back ground
Extinction
 With change in environmental conditions some species
disappear & other which are more adopted to changed
conditions take their place .This loss of specie which occur in
geological past at very slow rate is known as natural &back
ground extinction.

7. Natural Extinction7

8. Coextension
 The loss of one species leads to the loss of another in a china
effect . A small impact in the beginning of an extinction can
have an overall lager effect.
 Reason for extinction could be as a result of predator losing
its food source or if a key species become extinct & the
ecosystem become off balance.

10. Mass Extinction10

11. Planned Extinction
 Human controlled extinction were thought to be helpful full for the human
population but generally ended in the spread of deadly viruses.
 Example: Small pox extinct in the wild .polio nearly extinct but can be
found in some parts of the world.

13. Some Definition
 Rare species
 Vulnerable Species
 Endangered species
 Threatened Species
13

14. Rare species
 These are the species with naturally small population either localized or thinly
scattered which are always at risk from pests, pathogens predator & exotic
species.
 For example
 Clouded rheopard of hemlines is a area species.
 Mong seel is also present in six small air land.
 Indian bustard is rare species of bird.

17. Leopard17

18. Vulnerable Species
 Abundant population at present but lacking threatened with
depletion in number due to some factor.
 Example: Use of DDT for birds population no of addox antilog
continues to decline.

21. Example of Endangered species21

22. Threatened Species
 Threatened species is the one that is liable to become extinct
if not allowed to realize for biotic potential by providing
protection from human exploitation depletion of food habitat
destruction &exotic species.

24. Cause of Extinction24

25. Causes of Extinction
Major Cause
 Over Hunting & Over Harvesting
 Habitat loss
 Pollution
 Introduction of Exotic Species
 Climate change
Minor cause
 Low reproductive rate
 Loss of gene flow
 Limited Distribution rate
 Specie Specialization
 Collection for zoo &research l
