Populations of caribou show a cyclical fluctuation with predictable patterns in Norway. Reindeer populations are higher in the southern regions in winter months while populations are higher in the northern regions in the summer months. Infer the cause of
these predictable changes for the Norwegian reindeer populations.

Reindeer migrate from north to south in the winter months to reach more

The reindeer migrate from north to south in the summer months to reach
more fertile feeding grounds. They migrate to the north in winter months.
The reindeer populations migrate to an intermediate location in Norway to
mate and then diverge to the northernmost and southernmost regions to
avoid competition for food.
There are two species of reindeer in Norway. The northernmost species
reproduces in the winter, causing an increase in population size. The
southernmost species reproduces in the summer, causing an increase in
population size.
