To calcu-late the PPF, suppose that Crusoe puts all 8 hours into gathering fruit, so that he gets 36 pounds. But there is no time left for fishing, so he gets 0 pounds of fish. If he takes an hour off from gathering fruit, he gets 35 pounds of fruit and has an hour in which to fishâso he gets 4 pounds of fish.The rest of the PPF is con-structed similarly. 2.ut there is no time left for fishing, so he gets 0 pounds of fish.

Bears will eat for up to 16 hour/day during this peak season and finally their weight begins to rise. They may feed on 50,000-200,000 buffaloberries each day. One study recorded an increase of 0.6 kg (1.4 lbs) per day during a 16 day period. In places like Banff National Park, where buffaloberry is plentiful, researchers have reported as many as 9 grizzlies within 3.1 sq. km (1.2 square miles).
