Which statement about energy is false?Group of answer choices It includes work, plus anything that can be transformed into work. In chemical form, it is passed up the food chain, along with nutrients. It moves between the living and nonliving world. Because energy is neither created nor destroyed, ecosystems can run indefinitely without any input energy. Some ecosystems can function independent of the energy of sunlight.

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…
Which of the following is true about energy flow in ecosystems on Earth? 99% of energy that reaches the earth is used to drive the process of photosynthesis Only about 10% of energy is moved from one trophic level to the next, while the remaining is lost as heat A very small amount of solar radiation that reaches the earth is scattered or reflected The Law of Conservation of Energy states that energy cannot be destroyed, but it can be created in plants
