Answer:
The number of mice and caterpillars will decrease
Step-by-step explanation:
This is more of a biology question than a history question, but here goes:
- Can't be more crows: If there are more blue-jays, then they have to compete more for food, which would decrease populations if anything
- Mice will go down: one of their primary predators has increased in numbers
- Can't be more mice: more jays equals more dying
- Caterpillars will go down: again, one of their primary predators has increased in numbers
- Can't be more caterpillars: more jays equals more dying
Hope this helps, friend! Good luck!
