Detailed explanation-1: -Extinction of Plants and Animals 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: -Solution : Natural extinction, mass extinction and anthropogenic extinction.
Detailed explanation-3: -Background extinction rate, or normal extinction rate, refers to the number of species that would be expected to go extinct over a period of time, based on non-anthropogenic (non-human) factors.
Detailed explanation-4: -The background extinction rate (the continual rate of species loss as they succumb to naturally occurring environmental and ecological forces) is quite low, amounting to roughly one to five species per year when the entire fossil record is considered.
