Quizplus · Accepted Answer

The addition of another predator, the wild dogs, will increase the pressure on the population of field mice, leading to a reduction in their numbers in the short-term. This is because there are now more predators targeting the same prey. The migration of hawks or a tendency for hawks to prey on the dogs is unlikely as hawks and wild dogs occupy different niches in the ecosystem. An increase in the snake population is also unlikely as there is no obvious reason why the addition of wild dogs would lead to an increase in snake numbers.
