Explain how the use of a chemical designed to kill grasshoppers could reduce the population of peregrine falcons.
Butoxors [25]
Peregrine falcons have a wide diet, including many types of smaller birds. These birds eat bugs like grasshoppers. So, if the grasshopper population decreases, then the birds who are a food source to peregrine falcons will also have a lower population. This means that there is a lesser amount of food for the peregrine falcons to eat, so their population will decrease as well. 

Good luck with your problems!
