Question

Construct a graph based on the information

Background Information
Analysing data is crucial to understanding the effect of one species on another. Complete the following
data-analysis question.
The wedge-tailed eagle (Aquila audax) is a predator. It captures most of its prey on the ground by gliding
attacks. Its diet includes wallabies, native rats, small kangaroos, reptiles, birds, rabbits and carrion (dead
animals)
Aim – Write an aim for this investigation
Method – Using the data in Table 11.1, create a predator-prey line graph to demonstrate the
relationship between the populations of wedge-tailed eagles and native rats.

Discussion
1. Describe the trend(s) shown in your graph.
2. What is the limiting factor in this ecosystem.
3. Why is there a noticeable lag (delay) between the increases and decreases in the two
populations?
Conclusion - Write a summary statement outlining the relationship demonstrated by this data.
