Why are nonnative species a threat to biodiversity? check all that apply. they provide more niches for animals to live in. they do not have natural predators to regulate their population growth. they cause the climate in an area to become cooler. they provide food resources to native organisms. they compete with native organisms for resources.

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.  

Non-native species are the foreign organism introduced in any habitat. They are a threat to biodiversity as they do not have natural predators to regulate their population growth and compete with the native organisms for resources.

Due to human intervention or natural reasons some non-native species are introduced in the biodiversity that exhibits a negative effect on the ecology and the ecosystem of the area.

The invasive species are a threat to the domestic and the native species of the region, as they alter the habitat and the function it serves for the organism gets modified.  

Their growth threatens the original species of that area as they can act as a predator or parasite against the species thriving in that area already. They can also compete with the native species for the resources posing a threat to them.

Therefore, option 2. they do not have natural predators and option 5. they compete with natives are the correct options.
