This worksheet accompanies the children's book Wolf Island by Celia Godkin (available on Amazon at http://www.amazon.com/Wolf-Island-Celia-Godkin/dp/1554550084/ref=sr_1_1?ie=UTF8&qid=1294609325&sr=8-1). The book describes the changes that an island ecosystem encounters when a population of wolves suddenly leave the island. Deer are allowed to overproduce and the grass population dwindles. The book provides an excellent lesson for middle years science topics on succession. This worksheet acts as a followup to a teacher reading this book to the class. Discussion will include consumers, producers, succession, food chains and food webs.
