why are nonnative species a threat to biodiversity?\nthey often use up resources that other organisms need.\nthey are not able to successfully breed in the wild.\nthey release pollution into many environments.\nthey easily contract and spread diseases to other organisms.
Answer
Brief Explanations:
Non - native species can out - compete native species for resources like food, water, and space, which is a major threat to biodiversity. They don't necessarily release pollution, may breed well in the wild, and disease - spreading is not their most common threat mechanism compared to resource use.
Answer:
They often use up resources that other organisms need.
