Why are invasive species dangerous to the environment?

They mess up local ecosystem and if not eradicated they can take over the ecosystem. Example: pythons in the Florida Everglades. These snakes were released in the wild and they not only survived but flourished in this environment eating small animals in the glades and if that animal say frog gets eraticated the species above the food chain will die off from that area so on and so on
