Answer:
The Burmese python is a native species to the tropics in South and Southeast Asia and introduced in Florida, U.S. as a pet. But the python can grow very long in length and people released them in the everglades.
Python became an invasive species in Florida which is harmful for native species. Python do not have any natural predator in Florida and its population is uncontrolled naturally.
Python are affecting flow of energy in everglades as because of no natural predators they grow large in size and numbers and that will lack food for other animals and predators.
Hence, when other organisms and predators will not get enough food, it will completely change the normal food chain of the ecosystem.
