Question

which of the following describes both gelisols and alfisols?
i. typically contain permafrost
ii. contain large amounts of organic matter
iii. found in tropical rainforest biomes
i only
ii only
i and iii only
ii and iii only

Explanation:

• Analyze Statement I: Gelisols are known to typically contain permafrost, but Alfisols do not. So I is incorrect for describing both.
• Analyze Statement II: Both Gelisols (due to cold conditions slowing decomposition, preserving organic matter) and Alfisols (often in forested areas with organic input) contain large amounts of organic matter. So II applies to both.
• Analyze Statement III: Gelisols are in cold, permafrost - rich regions, not tropical rainforests. Alfisols are in temperate forests, not tropical rainforests. So III is incorrect.

Answer:

II only
