Answer

Brief Explanations:

  • Invasive species are non - native organisms that disrupt ecosystems. Option 1: Invasive species don't mainly pollute the environment; pollution is different from their ecological impact. Option 2: Invasive species aren't always predators; they can be competitors, etc. Option 3: Invasive species outcompete native species for resources like food, space, and mates, which reduces the variety of species (biodiversity) in an ecosystem. Option 4: Abiotic factors are non - living components, and invasive species don't "bring" abiotic factors in a way that makes them dangerous to the environment. So the correct option is the one stating they threaten biodiversity.

Answer:

They threaten biodiversity. (The option "They threaten biodiversity.")
