In recent decades, overfishing has led to large decreases in the sizes of shark populations. Biologists studying the effects of overfishing on marine ecosystems have hypothesized that a decrease in hammerhead sharks has led to a decrease in bay scallops.

Select two pieces of data that the biologists would most likely use to test their hypothesis.
