A team of students from UGA are completing a field study to determine the impact the American alligator has on ecosystems in places such as the Okefenokee Swamp
in South Georgia over a 3-month period. In one area, they have removed the
alligators and in another area they have left the alligators. What is the hypothesis
the students are testing?
