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.

All detritivores are decomposers because they both consume dead organisms. But not all decomposers are detritivores. Detritivores (detrit = wear down into bits, vore = to eat; have mouths and eat dead bits of plants and animals. Some examples include worms and certain insects (pill bugs, millipedes).rganisms that consume secondary consumers are called tertiary consumers, and so on. Some organisms consume by absorbing food (ex. fungi and bacteria). Some organisms consume by eating with special adaptations called mouths (and sometimes teeth or beaks).
