A new species, when introduced to an ecosystem, will compete with the indigenous species for food and resources. If the new species is predatory, it may also begin preying on the indigenous species, so the native populations will decrease sharply.

Why do exotic species sometimes take over an ecosystem?
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.
How can an exotic species threaten an ecosystem?
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.
How do organisms survive in an ecosystem?
Organisms survive in an ecosystem by being in a food chain or adapting to the resident food web. For an organism to survive in an ecosystem in needs to find a way to belong. Sometimes when an new organism is introduced to an ecosystem they adapt too well and they are classified as an invasive species. The organism will either have to adapt to the ecosystem or die out.
Species introduced to new geographic locations?
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.
What is a primary species?
A primary species is the first species to inhabit a new environment in the primary succession.

Plants introduced into new habitats in which they were not originally raised are?
Invasive species are different species, either plants or animals, which are purposefully or accidentally introduced into a new ecosystem. They can be good in some ways but bad in others because they usually don't have as many predators in the new ecosystem and can take over.
What are two ways species can be introduced to an ecosystem?
Two ways new species can be introduced to an ecosystem is by being endangered and having an injury. If an animal is endangered or has an injury it is allowed to be taken to a wild animal place that they hold if the animal is injured abandoned and endangered or has an disease or illness
What is a possible cause of an ecosystem undergoing primary succession?
It is when a species is introduced into a new area. It could be caused by humans moving species or migration.

Why species are important?
The pioneer species begins an ecosystem for succession such as lichens. They start an ecosystem after the previous was destroyed or start an all new one
What are 'introduced species'?
it has been moved to a new area.
