The difference between native and non-native species is that native species are from that area and non-native species are not from that area.
Competition: Introduced invasive species compete against native species for essential resources such as food and habitat.Predation: Introduced predators can have more impact on prey population than native predators, as prey may not have adaptions to escape or fight them.

Eventually, all native species had to have been introduced sometime. So, native species are introduced species that have been in the ecosystem for a long time, and it and the other organisms have adapted to each other.

It's an introduced species such as rabbits being introduced into Australia.
Preying upon native species competing with native species for resources displacing native species :)
Sheep are not native to Australia - they are an introduced species.
Yes. Donkeys are introduced, and not native to Australia.
Native plants are plants that belong to an environment (they have evolved there). Exotic plants are plants that have been imported from elsewhere in the world and are not natural to the environment in which they are now living.
Sometimes a non-native species can be introduced into an environment as a way to address an environmental problem. Other times these are introduced by accident.
In the first place, introduced species threaten the food supplies of native animals. Introduced species tend to breed more quickly than native species, so they eat more, often razing feeding grounds which would support native herbivores for months by eating vegetation right down to the roots. Secondly, many introduced species are predators, and native Australian animals have not developed effective defence adaptations against predators that are new to them. Introduced plant species tend to spread more quickly through native habitats, killing off native plant species which might provide the natural food of Australian animals.
Species that migrate are called migratory species, while species that are accidentally introduced into an ecosystem are called invasive species.
