Directions: Use the population data presented in graphs and tables to answer the corresponding questions. Graph 1: Growth of a Rabbit Population 1. What type of growth curve does Graph 1 show? The graph shows the growth of a rabbit population 2. According to Graph 1, what is the carrying capacity for the rabbit population in this area? 60 3. During which months were the rabbits in exponential growth? June? Table 1: Population of Mice and Snakes over Time Year Snakes Number of Mice Born Number of Mice Died 1960 2 1000 200 1970 10 800 300 1980 30 400 500 1990 15 600 550 2000 14 620 600 2001 15 640 580 4. Using the data in Table 1, determine which year saw the smallest amount of change for the mice population. 1960 5. What is the approximate carrying capacity for snakes according to Table 1? 30

Graph 2: Lynx and Hare Populations Over Time 6. According to Graph 2, what happened to the hare population after sharp rises in the lynx population? The hare population went up 7. In Graph 2, do the peaks and dips in the lynx and hare populations occur at the exact same time? Explain. The peaks and dips don’t happen at the exact same time but they happen shortly after one another. 8. Lynxes hunt hares for food. Using the information presented in Graph 2, predict what would happen to the lynx population if a disease killed all of the hares. If a disease killed al the hares then the lynxes population would decrease because hares are their main sources of fod. Graph 3: Two Fish Species Population Size Over Time
