Cane toads were released in Australia in 1935 to try and control the population of beetles that were damaging sugarcane crops. The toads spread rapidly and ate huge quantities of insects. The numbers of many native insect species declined.

Suggest an explanation for why the numbers of local insect species declined due to the cane toads.
