How the species become extinct
Answers
Animals and plants that are at risk of becoming extinct because of threats from changing environments or predators are considered threatened or endangered. An "endangered" species is any species in danger of extinction through all or a significant portion of its range.
Answer: Extinction is the termination of an organism or of a group of organisms usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively.More than 99 percent of all species, amounting to over five billion species,that ever lived on Earth are estimated to have died out.Through evolution, species arise through the process of speciation where new varieties of organisms arise and thrive when they are able to find and exploit an ecological niche and species become extinct when they are no longer able to survive in changing conditions or against superior competition....
