We are asked to evaluate two aspects from the population growth graph of three wild turkey populations in state parks.

First sub-question: Which population has stabilized at its carrying capacity?
- Lake Bemidji State Park population: The yellow series shows large fluctuations, with periods of rapid rise and decline, and there is no clear long-term plateau at a single high level. This indicates it has not stabilized at a carrying capacity.
- St. Croix State Park population: The red series eventually climbs toward higher values, but near the end it continues to rise rather than leveling off, so this population does not appear to be stabilized at a carrying capacity within the shown time frame.
- Blue Mounds State Park population: The blue series increases through time and then settles into a relatively narrow range after about the 1990s, hovering around a similar level with only small fluctuations. This pattern is consistent with stabilization at carrying capacity, where population size remains roughly constant despite environmental fluctuations.
- Not enough data to determine an answer: While some doubt could be raised, the blue series clearly demonstrates a long-term plateau, making this option unnecessary.

Second sub-question: What is the carrying capacity of this stabilized population?
- ~600: The stabilized blue population appears to level off around the mid-600s in hundreds of individuals, which corresponds to roughly 600 on the chart’s scale. This aligns with the observed plateau, where sizes stay near this value over time.
- ~500: This would be noticeably lower than the plateau seen in the graph; the data do not cluster around 500 for the stabilized period.
- ~800: The population does not remain near 800; the line stabilizes well below that value.
- ~350: The stabilized values are higher than 350, so this underestimates the plateau.
- Not enough data to determine the carrying capacity: Since the blue population shows a persistent plateau around 600, there is sufficient data to estimate the carrying capacity, making this option incorrect.
- ~700: While close to 700, the observed plateau centers closer to 600 than to 700, and the population does not consistently stay near 700.

In summary, the reasoning points toward the Blue Mounds State Park population as the stabilized one, with a carrying capacity inferred around ~600 based on where the blue line flattens and maintains that level over time. The other options either describe non-stabilizing trends, over- or under-estimates of the plateau, or claim insufficient data when a clear stabilization is visible from the graph.
