|
|
Both the native species and the non-native species thrive on the same food source.
|
|
|
The native species is immune to certain pathogens in the ecosystem.
|
|
|
Predators prey on both native and non-native species.
|
|
|
The non-native species has no natural enemies in the ecosystem.

Detailed explanation-1: -A native species and a non-native species are competing for resources within the same ecosystem. The non-native species is more likely to survive than the native species in which of the following situations? Both the native species and the non-native species thrive on the same food source.
Detailed explanation-2: -Which situation is an example of nonnative species introduction? A huge volcanic eruption in Washington destroyed many habitats.
Detailed explanation-3: -To be invasive, a species must adapt to the new area easily. It must reproduce quickly. It must harm property, the economy, or the native plants and animals of the region. Many invasive species are introduced into a new region accidentally.
Detailed explanation-4: -Keystone species have low functional redundancy. This means that if the species were to disappear from the ecosystem, no other species would be able to fill its ecological niche. The ecosystem would be forced to radically change, allowing new and possibly invasive species to populate the habitat.
Detailed explanation-5: -Increasing species diversity can influence ecosystem functions-such as productivity-by increasing the likelihood that species will use complementary resources and can also increase the likelihood that a particularly productive or efficient species is present in the community.
