The two measurements that can provide supporting evidence that changing the number of wolves in an ecosystem can affect the population of elk are:
**B. counting the size of the elk herd** - This directly measures the population of elk, which is the species in question.
**A. recording changes in vegetation** - Changes in vegetation can be an indirect indicator of the elk's grazing patterns, which can be influenced by the presence of wolves.
Together, these measurements can help demonstrate the relationship between wolf population dynamics and elk population and behavior in the ecosystem.
