Question

Cuban tree frogs eat smaller native frogs in the Florida Everglades. What does this scenario represent?

Answer 1

Although, you said scenario isn't that making the Tree frog a carnivore?

Answer 2

If the Cuban tree frogs came from Cuba (names can be deceptive sometimes; perhaps it was only discovered in Cuba but was endemic throughout the region), I'd say it represents an invasive species. But as the question is worded, there are other situations like 'competition' which it could be as well...
