◉Increasing density of tree and bush stems has a positive effect on
snowshoe hare abundance. Answer: True
◉Areas with more than 100,000 stems per hectare should have hare
densities approaching 4 hares per hectare. Answer: Cannot tell from

◉For the graph in Step 7 showing fish body lengths and the
percentage of tern diets that they comprise, which statement best
summarizes the trend shown in the graph?. Answer: The blue-grey
noddy's diet is composed primarily of smaller fish and the sooty
tern's diet is composed mostly of moderate sized fish.
