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.

What positive and negative impacts do aliens species have on ecosystems?
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.
Why allien invasive species are a problem in SA?
Alien invasive species are a problem in South Africa because they outcompete indigenous species for resources, disrupt ecosystems, and can lead to the decline or extinction of native plants and animals. They can also impact agriculture, forestry, and human health, causing economic and environmental damage. Management efforts are necessary to control their spread and minimize their negative impacts.
Why are some alien species a threat to ecosystems?
The two most common reasons non-indiginous species are threats to ecosystems are these:1) The new species takes resources, thus depriving indiginous species of those resources, and2) The new species upsets the predator / prey balance in the existing ecosystem.For example, if you were to introduce snakes in an area with no snakes, that could have the effect of depleting the population of rodents in that area, due to snakes' appetite for rodents. Because this is a new demand for rodents, you would be depriving birds of prey (for example) of the rodent food source, and you would be population INCREASE of those foodstuffs on which rodents feed. It is quite easy to see how this new species (snakes) could lead to further upsets in the ecosystem, both up and down the food-chain.
Why is alien plants bad for the environment?
Alien plants, also known as invasive species, can negatively impact the environment by outcompeting native plants, reducing biodiversity, altering ecosystems, and disrupting food chains. They may not have natural predators or controls in their new environment, allowing them to spread rapidly and crowd out native species. This can have far-reaching effects on the ecosystem's balance and health.
Can you give 6 examples of biodiversity loss?
Deforestation leading to loss of habitat for countless species. Overfishing depleting marine ecosystems and disrupting food chains. Pollution causing harm to various species and their environments. Climate change altering habitats and affecting the survival of many species. Invasive species outcompeting native species, leading to biodiversity loss. Habitat fragmentation isolating populations and reducing genetic diversity within species.

Why do alien speecies often thrive in their new ecosystems?
When an alien species enters into a new environment it has no natural predators. Anything that could eventually become a predator would be standoff-ish at first since the alien represents something new and is thus feared. Once the new predators realize how to kill the alien species their population will deminish and eventually become under control.
Differentiate Alien Species from 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.
What is an alien species in the US?
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.
