A scientist has tracked the population sizes of wolves and caribou within a national park. Assuming that there are no other prey species available to the wolves, how will the wolf and caribou populations change over time?
A. The wolf population will increase as
caribou numbers increase (although there will
be a slight lag).
B. The wolf population will increase
exponentially, regardless of the caribou
population.
C. The wolf population will decrease as
caribou numbers increase (although there will
be a slight lag).
D. The wolf population will fluctuate between
high and low levels, but this will be
independent of the caribou population.
E. The wolf and caribou populations will
fluctuate periodically, and the graphs of their
population size will match exactly (i.e., there
is no lag).
