Transcript text: Soil classification is partially determined by the presence of organic material, such as humus. Which would have more humus-a desert or a forest-and why? Check all that apply.
a forest because it has more trees to provide plant litter
a desert because it has soil with a larger particle size
a forest because it has more animals to mix the soil
a forest because the trees prevent rain from reaching the soil
a desert because the dry air decomposes plant litter
