### Example: Lynx and Hare

#### Graph Explanation:

The graph included in this example displays the population trends of the Snowshoe hare and the Lynx from 1850 to 1930. The y-axis on the left shows the number of hares in thousands, and the y-axis on the right shows the number of lynxes in thousands. The x-axis, marked in years, spans from 1850 to 1930.

**Key:**
- **Snowshoe Hare:** Represented by a blue line.
- **Lynx:** Represented by a red line.

Observations:
- There are notable cyclical patterns in the populations of both species.
- The peaks and troughs in the population sizes of the Snowshoe hare are more pronounced compared to those of the Lynx.
- Generally, the population peaks of the Lynx follow those of the Snowshoe hare.

#### Questions:

1. **What occurs to the Lynx population when the number of snow hares increases?**
   - The Lynx population typically increases following a rise in the Snowshoe hare population. This is likely due to the increased availability of food for the Lynx, which preys on the Snowshoe hare.

2. **Why does the number of lynxes decrease in the year 1925?**
   - The number of lynxes decreases in the year 1925 likely because the population of Snowshoe hares, their primary food source, has decreased. This reduction in food availability would consequently lead to a decline in the Lynx population.

3. **Between what two years is the hare population at its greatest?**
   - The hare population is at its greatest between the years 1865 and 1875. During this period, the graph shows the highest peak in the population of Snowshoe hares.

This example demonstrates the predator-prey relationship and how fluctuations in the population of one species can impact the population dynamics of another species.
