Correct answer: They threaten biodiversity.

Why: Invasive species can outcompete, prey on, or bring diseases to native species, cause hybridization, and alter habitats and ecosystem processes — all of which reduce native species richness and ecosystem resilience.

Why the other choices are incorrect:
- "They pollute the environment." — Not generally true. Some invasives can change nutrient cycles or water quality, but calling them pollutants is misleading.
- "They are always predators." — False. Invasives can be plants, herbivores, pathogens, or competitors as well as predators.
- "They bring abiotic factors." — Incorrect: abiotic factors are nonliving (temperature, soil, water); organisms don’t “bring” abiotic factors, though they can alter them.
