Exotic Species.
An alien species is a species that is not native to an area. An exotic species is native to an area but not common.
Exotic species are animals that are not native to the area. Lions and giraffes are exotic animals in Ohio but not in Africa.
exotic species
A native species originated from that area while an exotic species came from somewhere else.
New species are introduced into areas to either get rid of another animal e.g. the cane toad came to Australia to get rid of some kind of bug or and animal is accidentally taken to another country.
they are alike
Often the exotic species has fewer natural enemies in the new environment but competes for the same food supply and other necessities as the native species it displaces. Sometimes the exotic species is more adaptable or more aggressive and so pushes out a native species. Sometimes the exotic species reproduces at a higher rate or more successfully than does the native species.
When exotic species are introduced into a new ecosystem, they often don't encounter the same factors that controlled the exotic species population or growth that was in the original ecosystem.
When exotic species are introduced into an area these species can grow at exponential rate due to a lack of competitors and a lack of predators they may take over niches of native species and can eventually replace the native species completely
Exotic species are simply those that do not belong in your particular habitat. They are harmful because when they are introduced into your habitat they compete with some native species and threaten to make it extinct. Such is happening with the European starling and many native North America birds.
exotic species do not live in our country like koala and penguin
