I only know the natural predators of a humpback whale, although I'm sure other baleen whales share the same predators. The natural predators of a humpback whale are orcas (killer whales) and occasionally sharks. The attacks usually happen in humpback feeding ground and on calves. Orcas are a bigger threat than sharks.
Different species of animals have different social structures. Some are solitary; others live in groups. Kangaroos just happen to be a species that lives in groups. It could be theorised that kangaroos live in groups for protection. However, it should be remembered that, prior to European settlement, there were no natural predators of the larger species of kangaroos.
There are invasive species in many of the deserts around the world. Many times they do not have any natural enemies in their new environment and will eventually crowd out native species.
It is a wipeout of many species at once, normally by natural disaster or disease, i.e Dinosaurs by meteor. There's no telling if it will happen in the future.
If an endangered species were introduced into a nonnative habitat they might flourish as there are no natural predators. Of course, it could make them dwindle even more if there wasn't any food.
Extinct? Well, in order for a species to become extinct all its members have to die and not produce any offspring. If the environment becomes too hostile, or predators too numerous or good at hunting our doomed species, that may happen.
Mainly because of destruction of their habitat and from over-population of predators, and us humans hunting them.Many people are trying to prevent these things to happen =)
whay will happen is that they will not be able to fight there predators
Elephants are probably the largest living mammals on earth. They don't have any natural predators that can attack a full grown elephant. However, adolescent or young asian elephants can fall prey to adult Lions or Tigers. This can only happen if the youngster strays away from the herd.
Changes that happen without no help from humans they happen completely natural.
