Oh Deer! A variety of factors affect the ability of wildlife to successfully reproduce and to maintain their populations over time. These factors are called LIMITING FACTORS and can be disease, predator/prey relationships, impacts of weather conditions from season to season, accidents, environmental pollution, and habitat destruction. In this activity, we will simulate the interaction of a population of deer with the limiting factors of food, water, and shelter. (Double Line Graph) # Of Population/Limiting Factors Over Time Round # Deer Limiting Number Population Factors 28 0 26 1 24 2 22 3 20 4 18 5 16 6 14 7 12 8 10 9 8 10 6 4 2 Questions: 0 0 1 2 3 4 5 6 7 8 9 10 1. What are some things that animals need to survive? a. b. c. d. 2. From the pattern of the lines on the graphs, the populations of both the deer and the limiting factors tend to do what? 3. How are the limiting factors affected when the deer population : a. increases? b. why? c. decreases? d. why? 4. What is happening to the deer population when the limiting factors are: a. increasing? b. why? c. decreasing? d. why? 5. What is a current method used to keep deer populations from growing so large that they use up their limiting factors (especially food) and begin to die?
