Question

A wildlife biologist is studying kingfisher population changes at a particular lake as part of an effort to maintain ecological balance in the area. The biologist decides to use this graph created by another biologist: What questions should the biologist ask when evaluating the usefulness of this graph? Choose 2 answers What are the reasons for the differences in kingfisher populations from year to year? Is the graph specific enough to determine the current ecological status of the lake: Is there enough information to reach a conclusion about the kingfisher population? What were the other biologist's intentions when creating the graph? Which of the facts contained in the graph are the most important?

Explanation / Answer

The biologist should ask the following questions-

1. What were the other biologist's intentions when creating the graph?

2. Which of the facts contained in the graph are the most important?

The answers to the above two questions should be sought by the biologist. The first three questions like, there is no description in the graph about the population of kingfisher from year to year, seem redundant.

The graph indicates the comparison of kingfisher sightings over four years and on south and north side of lake during August each year. The biologist's aim is to maintaing the ecological balance. In such a scenario, he/she should aks the maker of the graph the real purpose of plotting this graph. The biologist may also seek information regarding the contents and crucial information in the graph. Therefore, the last two questions needs to be addressed by the biologist.
