Environmental Biology- 4 questions to answer and 1 reply to classmate question

In this interrupted case study, you will apply the scientific method to probe possible reasons behind declining marine iguana populations in the Galapagos Islands. Initially you are given rudimentary information and encouraged to generate wide-ranging hypotheses. You are then given further information to help refine your initial hypotheses into single, testable statements. As the case progresses, you will shift to an examination of experimental methods and data interpretation. Over the course of the case, both inductive and deductive reasoning will be applied in developing conclusions about factors influencing marine iguana populations.  Read through the following case study and answer any 4 questions posed within the case study:
