Why are nonnative species a threat to biodiversity? Check all that apply.

Answer 1

Answer:

The correct answers are the second and the fifth statements.

Explanation:

The non-native species are introduced in the community either as a consequence of human activity or because of natural range extensions. The majority of the non-native species exhibit deleterious ecological effects and are considered as invasive species. Almost all the ecosystems are at threat due to the deleterious effects of the introduced invasive species.  

The non-native species are the prime threat to the surroundings as they can modify habitats and change the ecosystem services and function, and may replace or crowd-out the local species. The non-native species are considered as the second-ranked major threat to biodiversity after habitat destruction like deforestation.  

These species threaten biodiversity as they can grow rapidly and can act as parasites or predators against the native species and do not possess any kind of natural predators so that the growth of the introduced species can be monitored. These species can act as competitors, as they compete with the local species for the resources available.
