The graph below shows the winter precipitation in Arizona from 1995 to 2002. It also shows the survival rates of Arizona pronghorn fawns for the same period. Which two years had the most precipitation?

• Which two years had the best survival rates for fawns?

• Using your knowledge of biotic and abiotic factors and information from the graph, give two reasons why precipitation and fawn population are linked.

• Predict what would happen to the fawn population if the precipitation rate continues to go downward in 2003.
