Question

1. unlike fossil fuels, biomass fuels ______.

○ are renewable resources
○ are not products of living things
○ do not release carbon dioxide
○ are buried beneath the surface

Explanation:

Fossil fuels are non-renewable, formed from ancient buried organic matter over millions of years. Biomass fuels come from recently living/biological materials (like crop waste, wood) that can be replenished quickly, making them renewable. Both release CO₂ when burned, both derive from living things, and some biomass can be buried, so the key distinguishing trait is renewability.

Answer:

A. are renewable resources
