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.
A native species originated from that area while an exotic species came from somewhere else.
exotic species
An exotic species is a plant or animal species that is not native to a specific region but has been introduced there, often by human activity. These species can disrupt local ecosystems, outcompete native species, and cause harm to biodiversity.
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 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
They are only in Africa.
a house sparrow is an exotic bird no a native bird!
