Quizplus · Accepted Answer

This figure suggests that smaller patch size increases extinction risk. The y-axis shows the probability of extinction, and as patch size decreases, the probability of extinction increases. The x-axis does not appear to have a strong correlation with extinction risk, so options B and D are less likely to be correct. Option A might be a tempting choice, as the patch sizes on the left side of the graph do seem to have a higher probability of extinction, but this trend does not hold for all patch sizes, so it is not a strong enough correlation to be the best choice.
