Answer:
• Chemical energy,: photosynthesis
• Mechanical energy,: erosion process
• Thermal energy,: photosynthesis
• Electrical energy,: fossil fuel combustion
Step-by-step explanation:
Chemical energy: in the photosynthesis process, the energy from the sun transform the water (H2O) and carbon dioxide (CO2) in glucose.
Mechanical energy: Through the erosion process, materials such as rocks, generate sediments that together with organic matter of the soil, help in the decomposition of organic matter.
Thermal energy: photosynthesis occurs with the thermal energy of the sun.
Electrical energy: through the combustion of fossil fuels, substances are produced that allow the production of electrical energy.
