Explanation:

To determine the correct answer, we analyze each option:

• "Their populations take needed resources from native plants and animals" is a valid reason as invasive species compete for resources with natives.
• "With no natural predators, they can rapidly overpopulate an area" is also a valid reason since lack of predators allows their population to boom.
• "An invasive species can overtake entire ecosystems and lead to a decrease in sustainability" is a valid reason as they disrupt ecosystem balance.

Since all the given options are valid reasons why invasive species are threats to ecosystems, the correct answer is the option that includes all these reasons.
