Question

Which statement is evidence of the effects of the availability of resources on the number of wolves or caribou?

A. When there were not enough caribou to eat in 1999, the wolf population increased.

B. When there was more food to eat in 1989, the number of wolves in a pack increased.

C. When there was less food available in 2009, the number of caribou and wolves remained constant.

D. When there was more food available in 2012, there was a decrease in the number of wolves and caribou.

Answer 1

Answer:

It's B.

Explanation:

B. When there was more food to eat in 1989, the number of wolves in a pack increased.

If there's less prey, then there will also be less predators. If there's more, then more predators.

Because, as seen in the graph, it's the only thing that makes sense.

(Then again, it looked kinda blurry to me.)

Still hope this helps though.
