Predator-Prey! vs. Key points of this activity: •Ratios and Food Pyramids •Competition •Biomagnification •Checks-and-balances •Survival of the fittest and Adaptations Ratios • Sustainability • Which ratio is best? Why? • How does this tie in to pyramid shape? Competition • Defined • Among species = Predation • Within species Biomagnification • California Condor and DDT • How did it apply in our rabbit/coyote game? Checks and Balances • Where have you heard this term before? • Apply it to Ecology and the rabbits/coyotes. Adaptation/Survival of Fittest • • • • Adaptation Natural Selection Evolution Know an example of adapting: – to predators – to competitors – in symbiosis Look it Up! (Get 2 examples of each) • • • • Life and the Molecule: Time-Life Ecology: Time-Life Plants: Ecology text: Mutualism Commensalism pp 394-397 pp 110-115 pp 147-153 pp 38-35 Parasitism LINKS Quick summary about Isle Royale Isle Royale population study report
