🔑:Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen. Chlorophyll, the green pigment in leaves, captures sunlight, initiating a series of chemical reactions in the chloroplasts. During this process, light energy is transformed into chemical energy, which is stored in glucose. The overall equation for photosynthesis can be summarized as 6CO2 + 6H2O + light energy → C6H12O6 + 6O2. This process is vital for plant life and contributes to the oxygen supply in the atmosphere.

🔑:Renewable energy sources are those that are naturally replenished and include solar, wind, hydroelectric, biomass, and geothermal energy. Solar energy harnesses sunlight using photovoltaic cells or solar panels, while wind energy converts kinetic energy from wind into electricity through turbines. Hydroelectric power generates energy from flowing water, often through dams. Biomass energy utilizes organic materials, and geothermal energy taps into heat from the Earth's core. These sources are essential for reducing reliance on fossil fuels and mitigating climate change impacts.
