The presence of an alien species may lead to inter-specific competition. An alien species may reproduce quickly due to a lack of predators of the species's ability to utilize resources that native species cannot. The alien species may even introduce diseases. Predation by the alien species can lead to a loss of biodiversity and some native endangered species may be driven to extinction.

One positive impact is that the alien species may be able to control a pest species in an ecosystem. It may also bring social and economical benefits such as the process of reforestation reducing soil erosion.However, the alien species may also have negative impacts on the ecosystem. It may lead to increased competition with native species, reducing the chances of survival for native organisms. Native species may be driven to extinction and this reduces biodiversity. The presence of an alien species may also upset the balance between predators and prey.
An alien is actually someone that is a resident of another country and goes to another country. Like a tourist is alien to the place he is visiting. Or someone who is excluded from a group is considered an alien to that groupYes but all these people are the same species an alien species is another species apart from Homo sapiens eg some species from another planet or galaxy.Or maybe in this question an alien species is a species that is not native to the US.
Many nonnative (alien) species are able to survive in new environments due to environmental similarity such as temperature, rainfall, seasonality and habitats where food and water is in abundance or enough to survive on and also the presence of other same species individuals with whom reproduction is possible. Another reason why nonative species survive in nonnative habitats is because of the lack of its native predators to keep its numbers in check and therefore they survive and reproduce quickly and outcompete native species.
