The data showed that recently the alligator population has decreased. How could the decrease in the alligator population affect the other populations? Be sure to explain whether the gar population, the diving duck population, a
the crab population will change, and why.

Since the alligator population decreased, this means there are less predators for the gar. Less predators for the gar mean the gar population will increase.  More gar also means more competition for the diving duck in terms of animals that eat crabs, and thus the diving duck population will also decrease.
