Question

which type of soil makes it most difficult for plants to thrive and decompose organic material?
sandy
acidic
water - logged
moist

Explanation:

To determine the soil type most difficult for plants to thrive and decompose organic material, we analyze each option:

• Sandy soil: Drains quickly but doesn’t inherently hinder decomposition.
• Acidic soil: Low pH can limit microbial activity (key for decomposition) and plant nutrient uptake, making it hard for plants and slowing decomposition.
• Water - logged soil: Lacks oxygen, but some plants tolerate it, and decomposition (via anaerobic microbes) still occurs.
• Moist soil: Ideal for most plants and microbial decomposition.

Acidic soil’s low pH disrupts microbial ecosystems (reducing decomposition) and plant nutrient absorption (harming growth) most significantly.

Answer:

B. acidic (assuming the options are labeled, with "acidic" as the correct choice)
