The invasive species can be introduced into a new ecosystem accidentally, intentionally, or it may happen naturally.
Explanation:
The invasive species are species that enter a new ecosystem to which they are not native. These species tend to be very aggressive competitors, often reproduce faster, and usually don't have any predators in the new ecosystem. Those things are all huge advantages for the invasive species to be able to spread out and establish itself in the new ecosystem. On the other hand, that is very bad to the native species, with their numbers usually sharply dropping.
- The invasive species can be introduced into a new ecosystem naturally, thus through migration, or because of human actions, with intention or by accident.
- Most of the invasive species turned out to be very damaging to the native species, such as the cats in Australia, the rabbits in numerous islands, or the rats all over the world.
- The invasive species though can introduce themselves to a new ecosystem, through migration. A good example of this is the migration of the smilodon into South America when it connected with North America. Being more specialized and more powerful predator, it is thought that it was directly responsible for the extinction of the marsupial predators like thylacosmylus, and the terror birds.
