Answer:
The mouse population will decrease
Step-by-step explanation:
- In this community, barn owls and snakes only consume mice.
- If the number of snakes increases, it means the consumption of mice will increase and thus decrease the number of mice in the community.
- We won't expect the number of barn owls to increase due to an increased competition by the increased number of snakes in the community.
- Therefore, in this case we would expect the mouse population top decrease while the number of barn owls population will also decrease due to increased competition by the increased snake's population.
