The figure titled 'Predator vs Prey Population Over Time' presents a scatter plot with data points highlighting the sizes of predator and prey populations over a period of 21 time points. The x-axis represents time, ranging from 0 to 20, and the y-axis represents population size.

In this figure:

- The predator population is denoted by red diamond-shaped markers with black edges.
- The prey population is depicted using blue circular markers with black edges.

Initially, at time 0, the prey population starts high at 200, while the predator population begins at a much lower value of 40. Over subsequent time points, a clear trend emerges where the predator population steadily increases, while the prey population correspondingly decreases.

Specifically, until around time 10, the predator population rises consistently from 40 to 80, reaching its peak at time 10. During the same period, the prey population declines from 200 to 110, showing a marked inverse relationship with the predator population.

Following time 10, both populations exhibit a reversal in their trends. The predator population starts to decline gradually, falling from 80 to 55 by time 20. Similarly, the prey population continues to decrease, but at a slower rate, from 110 down to 76 over the same period.

In summary, the figure visually demonstrates a typical predator-prey dynamic where an increase in predators leads to a decrease in prey, which is then followed by a decrease in predators as the available prey diminishes. This pattern is clearly represented by the intersecting trends of the two populations: a rising trend for predators and a falling trend for prey initially, followed by a declining trend for both as time progresses.

        "answer": "The prey population is always higher than the predator population.",
        "explanation": "Throughout the entire timeline, the prey population is consistently larger than the predator population in the figure."

    {
        "question": "Between time 10 and 20, which population shows a decreasing trend and which shows a steady decline?",
        "answer": "Both predator and prey populations show a decreasing trend.",
