exists and is an alternate of . Functional extinction means that there are not enough live animals (or animal protoplasm) of a certain species for the species to breed and survive.
If an animal is TRULY extinct, it means there are no more living individuals of that species. All are dead. However, the term has also been used in two other ways. The first is âextinct in the wildâ - there are still living individuals of the species, but only in captivity. The second is âecologically extinctâ - the numbers of the species in the wild have dropped so low that they can no longer fulfill their ecological role in that environment.
