Why are invasive species like the mongoose so successful in non-native environments?
Why are invasive species like the mongoose so successful in non-native environments?
- Native species in the new environment lack adaptations to defend against the invasive species. (correct)
- Invasive species are always successful due to genetic modifications.
- Invasive species have fewer predators in non-native environments.
- Invasive species are more aggressive and dominant than native species.
What usually determines if a species is considered invasive in a particular area?
What usually determines if a species is considered invasive in a particular area?
- The extinction of native species it causes or threatens. (correct)
- Its popularity with the local human population.
- The economic benefit it brings to the region.
- The size of its population in the new habitat.
Why might an introduced species be considered invasive in one area but not in its native habitat?
Why might an introduced species be considered invasive in one area but not in its native habitat?
- Predators in the native habitat keep the introduced species population in check.
- The introduced species evolves different traits in the new environment.
- The introduced species is more adaptable to non-native environments.
- Native species in the new environment have defense mechanisms against the introduced species. (correct)
