💡 Analysis & Explanation
Subject ▼
Geography.
Context ▼
Characteristics of Tropical Rainforests.
Details ▼
Statement I is incorrect; despite dense vegetation, the soil in tropical rainforests (often lateritic) is highly acidic and nutrient-poor due to intense leaching by heavy rainfall. Statement II is correct; high heat and humidity accelerate bacterial action, meaning organic matter decomposes rapidly and nutrients are immediately absorbed by plants rather than remaining in the soil.
