Question

Scientists have observed a trend in population changes of the snowshoe hare in Canada. About every 8 years, the number of hares falls sharply. One year later, the number of lynx in the same area falls also. The lynx is the main predator of the snowshoe hare. Scientists discovered that snowshoe hares rely on willow plants for food during the winter. When the population of the snowshoe hare gets bigger, they eat more of the leaves on the willows. Scientists also found out that the willow plants release a poison when they get eaten back too far. Which statement best describes what limits the size of the snowshoe hare population?

A. Other herbivores are the limiting factor because they compete for available food.

B. Predation is the limiting factor because the number of lynx causes the size of the snowshoe hare population to drop.

C. Space is the limiting factor because the hares have less space as their numbers increase and they cannot meet their needs.

D. Food is the limiting factor because the size of the snowshoe hare population depends mainly on the availability of willow plants in winter.
