Question

canine distemper is a highly contagious disease that can be lethal for wolves, especially for pups and older adults. canine distemper outbreaks occurred in yellowstone national park in 1999, 2005, 2008, and 2017. based on the graph, indicate how each distemper outbreak impacted wolf population growth. chart with outbreak year (1999, 2005, 2008, 2017) and columns: decreased by more than 25 wolves, decreased by fewer than 25 wolves, increased by fewer than 25 wolves, increased by more than 25 wolves, each with radio buttons

Explanation:

To solve this, we need to analyze the impact of canine distemper outbreaks on wolf populations. Since the problem refers to a graph (not fully visible here, but based on the context of disease affecting wildlife populations), we assume the graph shows wolf population changes during outbreak years. Canine distemper is a disease that typically reduces population size. For each year (1999, 2005, 2008, 2017), we check the population change:

Step1: Understand the Impact of Disease

Diseases like canine distemper (a lethal disease for wolves) should cause the wolf population to decrease, not increase. So we can eliminate the "increased by" columns.

Step2: Analyze Decrease Magnitude

We then determine if the decrease is more than 25 or fewer than 25 wolves per outbreak year. (Since the graph isn't fully shown, but based on typical outbreak impacts on wildlife populations, we assume the correct category for each year would be either "decreased by more than 25 wolves" or "decreased by fewer than 25 wolves" depending on the graph's data. However, as the graph is partially visible, we note the process: eliminate increase options, then choose the correct decrease magnitude per year.)

Answer:

(Note: Since the graph is not fully visible, but following the logic: For each outbreak year (1999, 2005, 2008, 2017), the wolf population size decreased (so select the "decreased by..." columns). The exact "more than 25" or "fewer than 25" would depend on the graph's data. For example, if the graph shows a significant drop, it might be "decreased by more than 25 wolves" for each year, or the appropriate magnitude. But based on the problem's context, the key is that disease outbreaks reduce population, so eliminate "increased" columns and choose the correct decrease magnitude per year from the graph.)
