A. Habitat X
B. Habitat Y
C. Habitat Z
D. Habitats X and Y
A. Habitat X

C. Students 2 and 4
D. Students 3 and 4
C. Students 2 and 4
Using Table 3 and Figure 1, which species shows the greater percent increase in average Behavior 5 display time when moving from its single-species habitat to the mixed-species Habitat Y, and how does that species' average perching height change between those habitats?
A. Striped; perching height increases
B. Spotted; perching height increases
C. Striped; perching height decreases
D. Spotted; perching height decreases
A. Striped; perching height increases
In Habitat Y, striped frogs displayed Behaviors 2 and 3 a total of 10 and 7 times, respectively (Table 2). If striped frogs in Habitat X were to maintain the same Behavior 2:Behavior 3 ratio observed in Habitat Y, about how many Behavior 2 displays would be expected in Habitat X given the observed 13 Behavior 3 displays there?
A. 17 B. 19 C. 13 D. 26
B. 19
Consider each species' change from its single-species habitat to the mixed-species habitat Y. Which species both perches higher on average (Figure 1) and shows fewer species-specific behavior displays (Table 2) in Habitat Y than in its single-species habitat?
A. Striped only
B. Spotted only
C. Both species
D. Neither species
C. Both species
Define the normalized display index as (average Behavior 5 display time in seconds) / (average perching height in meters). Using Table 3 and Figure 1, which species-habitat combination has the smallest normalized display index?
A. Striped X
B. Striped Y
C. Spotted Y
D. Spotted Z
C. Spotted Y
