The graph shows one possible answer; students will have their own values. The figure should show log-transformed mass on the y axis and log-transformed survival on the x axis. The points they plot should form a negative slope.

-A biologist studies a population of birds for 25 years. Each year the biologist records the amount of rainfall and the density of birds (number of birds per 100 square metres). Additionally, the biologist determines the survival rate for eggs laid that year. The biologist then plots egg survival rate against both rainfall (graph a) and bird density (graph b). In each plot the individual points represent the data for one year of the study. Based on these data, does this population of birds appear to have positive density-dependent population regulation, negative density-dependent population regulation, or density-independent population regulation? As part of your answer, list the prediction for each type of population regulation and explain whether the data meet that prediction.
