Question

under specific conditions over thousands to millions of years, what can dead organisms form through fossilization? macromolecules glucose fossil fuels seawater

Explanation:

Dead organisms under specific conditions over long periods (thousands to millions of years) undergo fossilization. Fossil fuels like coal, oil, and natural gas are formed from the remains of ancient plants and animals through this geological process. Macromolecules are large biological molecules (e.g., proteins, nucleic acids) formed in living organisms. Glucose is a simple sugar (a monosaccharide) produced by photosynthesis in plants. Seawater is a mixture of water and various salts found in the oceans. Only fossil fuels match the description of what dead organisms form through fossilization.

Answer:

Fossil fuels
