Several pet Burmese pythons escape a breeding facility when a hurricane destroys the building. With a limited number of predators their population quickly grows. Declines in native animal populations are severe. This is an example of what?

invasive species

Explanation:

Invasive species are those that are not usually belonging to a said population. Aside from a few of them escaping a breeding facility during a hurricane some were also placed there by persons who used to own them as pets and could not care for them anymore. These snakes that were not native to the are began feeding and existing in an ecosystem that is not their own. The natural balance of the eco-system was interrupted and cause the biodiversity to rapidly decline. This is because the pythons do not have a natural predator in the Florida everglades and can reproduce and grow unchecked. Wildlife conservationist are now working to reduce these populations and trying to stabilize the ecosystem.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
