Final answer:
The relationship between Snowshoe Hares and Lynx is a predator-prey dynamic that demonstrates a positive correlation, where fluctuations in hare population sizes influence lynx population sizes, and vice versa.
Step-by-step explanation:
The relationship between Snowshoe Hares and Lynx is an example of a predator-prey dynamic. In this ecological interaction, the population sizes of the two species are interdependent, where an increase in the hare population often gives rise to an increase in the lynx population, due to more available food. Conversely, as the lynx population increases, it can lead to a decrease in the hare population due to higher predation. This cyclical interaction typically exhibits a positive correlation because the population sizes of both species are connected; as the prey (hares) population increases, the predator's (lynx) population also tends to increase, although after a time lag. Hence, when the lynx population is low, the hare population starts to increase because of lowered predation pressure, initiating the cycle again.
Thus, based on the given data and the understanding of predator-prey relationships, the answer to the student's question would be A) Positive correlation. This is supported by research that demonstrates significant fluctuations in the population sizes of both hares and lynx, with periods where both populations rise and fall in a correlated manner over time.
