Detailed explanation-1: -Extinction is the death of all members of a species of plants, animals, or other organisms. One of the most dramatic examples of a modern extinction is the passenger pigeon.

Detailed explanation-2: -Extinction is the complete disappearance of a species from Earth. Species go extinct every year, but historically the average rate of extinction has been very slow with a few exceptions.

Detailed explanation-3: -There are two main types of extinction: Mass extinction and background extinction. Mass extinction has only occurred five times in history. These are short and sudden phenomena caused by unnatural catastrophes such as asteroid impacts or volcanic eruptions. Over 50% of all species are wiped out at once.

Detailed explanation-4: -Extinction is defined as the end of an organism or of a group of organisms, normally a species. The moment of extinction is considered when the last individual of the species die, although their capacity to breed and recover may have been lost much before this point.
