Answer:
The quick rate of reproduction and lack of predators.
Explanation:
The rabbits exhibit a quick rate of reproduction in comparison to the native marsupials, which exhibits a gradual reproduction rate. Thus, in a brief time duration, they were able to outnumber the native populations, and thus eating their food, and occupying their homes.
The lack of predators is another factor that has resulted in the rapid upsurge of the rabbit's population. The predators in Australia are not so common, and besides from the introduction of the species like the fox, dingo, and the feral cats, there are not any others. Of these, the populations of the dingo are very few and are just confined to some of the parts of Australia, while the feral cats and the foxes were not in large ratios in the 1800s, due to which the rabbits overpopulate.
