Question

An eagle is a predator for squirrels. a new law stops humans from hunting eagles, and the eagle population increases. what will happen to the squirrel population?

Answer 1

As eagle feeds on squirrels, an increase in the number of eagles, will obviously lead to a decrease in the number of squirrels. 
If eagle population was declining, then squirrel population must have been on a rise. Implementation of this new law will keep squirrel population in check, and help in conservation of eagles. 

Answer 2

The squirrel birthrate will decrease
