Answer
Step 1: Identify the position of energy conversion in the flowchart.According to the picture details, position
is after the energy has been transferred from the Sun to plants and then to wood. This position is likely to be after the wood stage but before the electricity-generating devices.Step 2: Determine the type of energy conversion at position
.Since the energy has been transferred from the Sun to plants, which is a process of photosynthesis, the energy in the plants (and thus in the wood) is stored as chemical energy. The next step in the flowchart involves burning wood, which releases the stored chemical energy.Step 3: Analyze the options in relation to the energy conversion at position
.A. Conversion of chemical energy to heat energy - This is likely the correct answer, as burning wood releases the chemical energy as heat (and light).B. Conversion of chemical energy to electric energy - This conversion typically occurs in an electricity-generating device, not during the burning of wood.C. Conversion of chemical energy to radiant energy - While burning wood does release radiant energy (light), the primary energy form released is heat.D. Conversion of radiant energy to chemical energy - This describes photosynthesis, not the burning of wood.E. Conversion of mechanical energy to chemical energy - There is no mechanical energy involved in the burning of wood.Step 4: Select the correct answer based on the analysis.The correct answer is A. Conversion of chemical energy to heat energy, as this is the primary form of energy released when wood is burned.Final Answer: A. Conversion of chemical energy to heat energy.
