The number of pythons found throughout Everglades National Park has increased in recent years. These huge snakes are not native to Florida and are believed to have been released into the wild by pet owners. Wildlife biologists have initiated attempts to capture and remove these pythons. Which statement best explains the biologists’ reason for removing these pythons from the Everglades?

• The pythons could upset the territorial boundaries of native organisms.

• The pythons could adapt to overcome diseases common to native snakes.

• The pythons could prey on native organisms and cause native populations to decline.

• The pythons could begin to interbreed with native snakes and produce a more successful species.
