Which statement distinguishes live fuels from dead fuels?

Which statement distinguishes live fuels from dead fuels?

• A. Live fuels are living vegetation (green grasses); dead fuels are non-living material (duff, litter, fallen wood).
• B. Live fuels are dry, dead materials.
• C. Live fuels are mineral soil exposed after burn.
• D. Live fuels are ash residues.

Answer: (A)

The main idea is distinguishing fuels by whether they are alive or dead. Live fuels are living vegetation (green grasses, shrubs, foliage), while dead fuels are non-living material (duff, litter, fallen wood). This distinction matters because living fuels usually contain more moisture and behave differently in a fire than dry, dead fuels. The other statements describe conditions or materials that aren’t the defining contrast between live and dead fuels—such as referring to dry dead material, exposed mineral soil after burning, or ash residues.
