Which term refers to fuels located near the ground, including grasses, shrubs, timber litter, and slash?

Explanation:
Fuels are categorized by where they sit relative to the ground. Those that lie on the surface—grasses, shrubs, timber litter, and slash—are called surface fuels. They burn as a layer on the ground, driving the flame spread across the forest floor and shaping how a fire behaves on the ground, including rate of spread and flame height. Ground fuels would be below the surface (like duff or buried organic matter), crown fuels are in the canopy above, and subsurface fuels refer to underground materials. So the described materials fit the surface fuels category because they occupy and burn right at the ground level.
