Predicting Population Sizes on Isle Royale

Scientists counted the number of wolves and moose on Island Royale every year starting in 1959. Here is the data for 1959 and for 2010.

In order to compare data from two populations, scientists plot the data using two different y-axes on the same graph. The y-axis on the left side of the graph below is the scale for the size of the wolf population. The y-axis on the right side of the graph below is the scale for the size of the moose population.

Questions

Please answer the questions below.

Sketch the shape of the graph that you predict you will see for the size of the wolf population between 1959 and 2010.

In a different color, sketch the shape of the graph that you predict you will see for the size of the moose population between 1959 and 2010.

Note: Draw your sketch in the sketchpad below
