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 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

Explanation:

• Humus is formed from decomposed plant and animal matter. Forests have more trees (plant litter) and more animals (mixing soil and contributing to decomposition) compared to deserts.
• Deserts have less plant and animal matter due to harsh conditions. Larger soil particle size in deserts doesn't lead to more humus. Trees in forests don't prevent rain from reaching soil in a way that would increase humus (rain is actually beneficial for decomposition processes in forests). Dry air in deserts doesn't decompose plant litter effectively (decomposition is slower in dry conditions).

Answer:

a forest because it has more trees to provide plant litter, a forest because it has more animals to mix the soil
