- Which of the following terms identifies a singular path for the flow of energy within an areaInterpreting 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…support or refute the following statements based on what you learned about energy flow, biogeochemical cycling, decomposition, trophic levels, and keystone species. You may add a diagram or illustration to support your answer. Shark fin soup can cause the collapse of coral reef ecosystem
- The biogeochemical cycles are: Thermodynamic processes that end in the same process in which they started. They are cycles that describe the different types of energy in an ecosystem. They are phases through which the chemical elements pass in the form of molecules through the air and water.
