In 1859, two dozen rabbits were introduced to Australia. By 1953, there were an estimated one billion rabbits in Australia. The addition of the rabbits to this established ecosystem caused many problems, including a huge decrease in native plants. This left little food for native animals. Evaluate the effects of the introduction of the rabbits on the ecosystem. A) The genetic diversity improves an established ecosystem. B) The importation of genetic variation leads to the formation of a new species. C) The introduction of non-native species, with no known predators, upsets a balanced system.
