Ecology, PCB 3043 Practice Exam #3 questions and answers

Ecology, PCB 3043 Practice Exam #3 questions © John Cozza and FIU—for FIU PCB 3043 enrolled students ONLY! PLEASE READ How to get the most out of this exam: this practice exam contains the kinds of questions I might ask on the actual exam, about similar material. However, it in no way implies that the question types will be in the same proportion on the actual exam, or this is the only material that will be covered. A few questions on this practice exam may be about material we didn’t cover this term. As stated in the syllabus and in class, the actual exam could include anything we covered or did in class, and the corresponding coverage of that material in the book, including additional relevant examples. Research shows that this exam will help you only if you do the problems, and after you have studied the material actively. If you try to do it before you understand most of the material, or just read it over, or do it after seeing the answers, it will not help you as much or at all. Studying the answers will not help you at all. Please respect the work that went into writing this exam and making it available for you to use. The exam is copyright of John Cozza and belongs to FIU. It is not yours to share outside of our course or to sell, especially not to for-profit websites that then turn around and re-sell somebody else’s work to other students. If anyone one is caught doing this (and we will use all available tools to check), they will be prosecuted to the extent the law allows, a note will be put in their file (not a good thing for potential professional schools or employers to know), and future practice exams may not be made available to anyone.
