Based on the graph, did the zebra population growth rate (dN/dt) differ in the years 1985 and 2003? Why or why not? (Hint: dN/dt is equal to the slope of the curve showing population size, N, over time, t.)

Transcribed Image Text:**Wildebeest and Zebra Populations in the Serengeti (1950s-2010)**
This graph displays the population trends of wildebeest and zebra in the Serengeti from the 1950s to 2010. The y-axis represents the population size, ranging from 200,000 to 1,400,000. The x-axis shows the years, beginning from the 1950s to 2010.
- **Key Symbols**:
- Circles (○) represent the wildebeest population.
- Triangles (▲) indicate the zebra population.
**Observations**:
- The wildebeest population begins with a significant rise starting around the early 1960s and peaking around 1980, coinciding with the "vaccination campaign" marked on the graph.
- After 1980, the wildebeest population stabilizes and remains relatively constant through to 2010.
- The zebra population remains relatively stable with minor fluctuations from the 1950s through 2010. No dramatic changes occur in comparison to the wildebeest.
This graph highlights a substantial increase in wildebeest populations post-1960s, corresponding with efforts in wildlife disease control, while zebra populations show less variation over the same period.
