Question

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. a forest because it has more trees to provide plant litter B. a desert because it has soil with a larger particle size C. a forest because it has more animals to mix the soil D. a forest because the trees prevent rain from reaching the soil E. a desert because the dry air decomposes plant litter

Answer 1

Answer: Correct options are A, C and D

A. a forest because it has more trees to provide plant litter

C. a forest because it has more animals to mix the soil

D. a forest because the trees prevent rain from reaching the soil

Explanation:

Humus simply refers to organic matter, and the quantity of organic matter in a habitat depends on the extent of life activities done there.

Deserts, unlike forests have minimal life activities (as few plants and animals thrive in it). Thus, forests have more humus than deserts.
