Organic matter that can be burned to create energy includes wood, crop residues, animal manure, and biomass such as algae or switchgrass. When burned, these materials release heat energy that can be harnessed for various applications like electricity generation or heating. This process is known as biomass combustion.
Producers get matter by converting sunlight into energy through photosynthesis. This energy is used to create organic compounds from inorganic materials such as carbon dioxide and water.
Coal gets its energy from the sun. Millions of years ago, plants and organic matter absorbed energy from the sun through photosynthesis. Over time, this organic matter was buried and compressed, forming coal. When coal is burned, it releases the stored energy from the sun in the form of heat and light.
Coal is formed from the decomposition of organic matter buried deep underground over millions of years. The process involves the conversion of solar energy into chemical energy through photosynthesis in plants, which is then transformed into potential energy as the organic matter is buried and compressed. Finally, when coal is burned, the potential energy is converted into thermal energy and released as heat.
Fossil fuels are formed from organic matter that originally obtained its energy from the sun through photosynthesis. This organic matter stored the sun's energy in the form of chemical bonds, which is released as chemical energy when the fossil fuels are burned. So, the chemical energy in fossil fuels can be traced back to the sun's energy.
Both wood and coal are derived from organic matter that originally came from plants. This organic matter stored energy from the sun through photosynthesis, which is then released when the wood or coal is burned as fuel.
