To do The classical energy flow example Silver Springs, in central Florida is famous amongst ecologists as the place where Howard T. Odum researched energy flow in the ecosystem in the 1950s. Odum (1924-2002) was a pioneer ecologist working on ecological energetics. This was the first time an energy budget measurement was attempted when Odum measured primary productivity and losses by respiration. (Later, near the end of a long and illustrious career, he and David Scienceman developed the concept of emergy (embodied energy) which is a measure of the quality and type of energy and matter that go into making an organism.) Figure 2.3.14 shows the energy flows and biomass stores measured by Odum at Silver Springs. This simple community consists of algae and duckweed [producers); tadpoles, shrimps and insect larvae [herbivores); water beetles and frogs (first carnivores]; small fish (top consumers); and bacteria, bivalves and snails (decomposers and detritivores]. Dead leaves also fall into the water and spring water flows out, exporting some detritus.A company is going to produce an item in four different production plants. Labor needed, materials used, and production cost in each production Plant 1 Plant 2 Plant 3 Plant 4 plant, to produce one unit, are different and provided below: Production quantity Labor (hr) Materials (lb) Cost/unit PLANT 1 $5 PLANT 2 5 $8 PLANT 3 3 8 $7 PLANT 4 6 1 $5 The company has to produce at least 350 units at plant 2. The demand is forecasted to be 1000 units. The total available labor and materials are 5000 hours and 4000 pounds, respectively. Assume that we want to minimize the production cost; by using Solver, calculate how many units the company needs to produce in each production plant.
