What is Extinction?
Hey Readers, How’s your day😊? Have you ever wondered that you’re enjoying and exploring social media in the mobile phone but when you wake up the next day and find no evidence of your mobile phone I think you will get a heart attack😂 this same scenario applies with the extinction of any organism or any species you see in your Environment.
Today I am gonna explain you about extinction and it’s types. So let’s begin the journey.
What is Extinction?
Many times, organisms are associated with each other in an obligatory way. In such cases, the extinction of one variable leads to loss
of associate variety from the ecosystem. e.g., the Extinction of host fish causes the extinction of unique parasites. Coevolved plant-pollinator,
also will have such a threat.
We are aware of the threat to diversity and the loss of species from earth. When any species is totally eliminated from the earth, it is called extinct. e.g. Dinosaurs.
When the number of members of a species starts dwindling (decrease), it is said to be endangered. The International Union for Conservation of Nature and Natural Resources (IUCN) maintains a Red Data Book also known as Red List, where the conservation status of plant and animal species is recorded.
Every speices or organism you see in this enviorment are important for your life and you are important for their life
If you think that humans are supreme speices then you don’t know then you don’t know the power of ants.
Types of Extinction:
- Extinct (EX), a designation applied to species in which the last individual has died or is not recorded.
- Extinct in the Wild (EW), a category containing those species whose members survive only in captivity
- Critically Endangered (CR), a category containing those species that possess an extremely high risk of extinction with very few surviving members (50).
- Endangered (EN), a designation applied to species that possess a very high risk of extinction as a result of the rapid population the decline of 50 to more than 70 percent over the previous 10 years (or three generations).
- Vulnerable (VU), a category containing those species that possess a very high risk of extinction as a result of the rapid population the decline of 30 to more than 50 percent over the previous 10 years (or three generations).
- Near Threatened (NT), a designation applied to species that are close to becoming threatened or may meet the criteria for threatened status in the near future.
- Least Concern (LC), a category containing species that are pervasive and abundant after careful assessment
- Data Deficient (DD), a condition applied to species in which the amount of available data related to its risk of extinction is lacking in some way.
- Not Evaluated (NE), a category used to include any of the nearly 1.9 million species described by scientists, but not assessed by the IUCN ( International Union for Conservation of Nature).
