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 and multiple - choice options about wolf population change during distemper outbreak years: 1999, 2005, 2008, 2017 with options like increased by more than 25 wolves, increased by fewer than 25 wolves, decreased by fewer than 25 wolves, decreased by more than 25 wolves

Explanation:

Step1: Analyze 1999 Outbreak

In 1999, the wolf population was growing but the increase was less than 25 (from graph trend and options, the "increased by fewer than 25" is selected, which matches as the growth rate slowed but still increased slightly).

Step2: Analyze 2005 Outbreak

In 2005, the population dropped by more than 25 (graph shows a sharp decline, so "decreased by more than 25" is correct as per the selected option).

Step3: Analyze 2008 Outbreak

2008 also had a significant drop, more than 25 wolves decrease (matches the selected "decreased by more than 25" option from the graph's sharp decline).

Step4: Analyze 2017 Outbreak

In 2017, the decrease was fewer than 25 (graph shows a milder drop, so "decreased by fewer than 25" is selected, which aligns with the option).

Answer:

• 1999: Increased by fewer than 25 wolves.
• 2005: Decreased by more than 25 wolves.
• 2008: Decreased by more than 25 wolves.
• 2017: Decreased by fewer than 25 wolves.
