Question

10 multiple choice 1 point critics of this story will argue that one of the factors that contributed to the population crash of the deer was a severe winter that created snow too deep for many of the reindeer to dig through for food. this would be an example of what kind of growth limiting factor? density independent density dependent clear my selection 11 multiple choice 1 point if this severe winter (mentioned in the previous question) never happened, do you think there would have still been a dieback? explain. no, because all of the food would still have been alive if there had not been a severe winter (as evidenced by the enormous, healthy lichen patches in 1957). yes, because the deer did not have enough food even before the severe winter (as evidenced by the barren (empty) lichen patches in 1957). no, because a predator would have swam across the water to get to the island and killed some of the deer before they ate all the food.

Explanation:

1. For question 10: A severe winter is a non - living environmental factor that affects the deer population regardless of its density, so it is a density - independent growth limiting factor.
2. For question 11: The barren lichen patches in 1957 suggest that the deer already had a food shortage problem before the severe winter, so even without the severe winter, there would likely still be a dieback.

Answer:

1. A. Density independent
2. Yes, because the deer did not have enough food even before the severe winter (as evidenced by the barren (empty) lichen patches in 1957).
