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.

Nonnative species may arrive without the predators that kept their populations in check, allowing them to grow rapidly and disrupt ecosystems. They can also compete with native species for food, space, and other resources. Providing more niches or food is not the typical reason they threaten biodiversity, and they do not generally cause an area’s climate to become cooler.
