Form of energy Kcal/m/yr Efficiency of energy transfer (%) Sunlight 600,000 n/a Chemical energy in producers 6,585 Chemical energy in primary consumers Data from: 1. M. Tal, Energy Flow in the Sat Marsh Ecosystam of Georgia. Ecokogy 43:614-24 (1962). 81 a. Calculate the efficiency of energy transfer by the producers. That is, what percentage of the energy in sunlight was converted into chemical energy and incorporated into plant biomass?

Question
Interpreting Data In a classic study, John Teal measured energy flow in a salt marsh ecosystem. The table below shows some of his results. Form of energy Kcal/m?/yr Efficiency of energy transfer (%) Sunlight 600,000 n/a Chemical energy in producers Chemical energy in primary consumers 6,585 81 Data from: J. M. Teal, Energy Flow in the Salt Marsh Ecosystem of Georgia. Ecology 43: 614-24 (1962). a. Calculate the efficiency of energy transfer by the producers. That is, what percentage of the energy in sunlight was converted into chemical energy and incorporated into plant biomass? b. Calculate the efficiency of energy transfer by the primary consumers. What percentage of the energy in plant biomass was incorporated into the bodies of the primary consumers? What became of the rest of the energy? c. How much energy is available for secondary consumers? Based on the efficiency of energy transfer by primary consumers, estimate how much energy will be available to tertiary consumers. d. Draw a pyramid of production for the producers, primary consumers, and secondary consumers for this ecosystem (see example in your textbook).
