Question

which fuel source contributes to greenhouse gas production?
○ fossil fuels
○ algae biofuel
○ soybean - based biofuel
○ ethanol - based biofuel

Explanation:

Fossil fuels (coal, oil, natural gas) release carbon dioxide and other greenhouse gases when burned, contributing to greenhouse gas production. Algae, soybean-based, and ethanol-based biofuels are generally considered lower-emission or carbon-neutral alternatives as their carbon release is offset by plant growth during their lifecycle.

Answer:

fossil fuels
