Question
Identifying the Role of Organisms in Soil Classification
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
