Limestone is a sedimentary rock that is composed primarily of calcite. It forms from both the chemical precipitation of calcium carbonate and the transformation of shell, coral, fecal and algal debris into calcite during diagenesis.
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.

One cannot catch a limit, process the fish or give them away to someone else, and go back and harvest more of the same species during a 24-hour period which runs from midnight to midnight. Say an individual is fishing from 8:00 pm to 3:00 am-they may only have a daily creel limit in their possession while afield. They could, however, stop fishing before midnight and drop their catch off at their campsite* or home and return after midnight and catch another limit.
