Introduced from Asia More Than 5,000 Years Ago, Dingoes (Wild

Introduced from Asia more than 5,000 years ago, dingoes (wild dogs) are now considered an "honorary native species" in Australia.They are the largest predators in the country.Like wolves, they hunt in packs and can bring down prey the size of buffaloes.Where dingoes are scarce, foxes and cats have caused the extinction of 20 mammals and threaten many more.Where more dingoes are present, fox and cat numbers are low, and mammal populations are protected.But farmers want to eradicate dingoes, which sometimes prey on sheep.Which would likely happen to the ecosystem if dingoes were removed?

A) Foxes and cats would both be top predators, and the ecosystem would stabilize.
B) Foxes and cats would both be top predators, and more species would go extinct.
C) Foxes and cats would vie for top predator status; the winner would stabilize the ecosystem.
D) The ecosystem would be unstable because sheep would overpopulate it.
E) The ecosystem would become more diverse because dingoes would not be removing organisms.
