FNR 103 INTRODUCTION TO ENVIRONMENTAL CONSERVATION REVIEW SHEET FOR FINAL EXAM The following are the main topics and terms covered since the start of class. If you know the definitions of these terms, and are generally familiar with the ideas, you should be prepared for the exam. When an example was given in class of a specific concept, know the general facts about the example, and what topic was being illustrated. Use the outlines given at the start of class, and materials shown as overhead slides as guides. The book should be used for review of topics that were not clear in class. ________________________________________________________________________________ Material covered in first and second exam (about ½ of final) 1.
