Which term describes non-renewable resources formed from ancient plants and animals?

The term that describes non-renewable resources formed from ancient plants and animals is "fossil fuels." Fossil fuels include coal, oil, and natural gas, which were created over millions of years through the decomposition of organic matter under heat and pressure in the Earth's crust. These resources are called non-renewable because they take millions of years to form and are being consumed much faster than they can be replaced.

In the context of energy production, fossil fuels are significant sources of energy but raise concerns about environmental impact due to carbon emissions and pollution. Understanding fossil fuels is crucial in discussions about energy usage, sustainability, and environmental science.
