One of the finch species has a slightly smaller, weaker beak. is this species 1 or species 2? support your answer with information from the graph. species:

The picture you posted with the question is not the correct graph that goes with this specific question. However, I do know the picture and am familiar with this question from experience. 

More of species 1 finches are at the low strength end of the graph. Also because it has a weaker beak than species number 2, except on the graph where the two lines do overlap.
