Which of the following best describes how temperature and rainfall influence the type of forest biome that develops in a region?

• A. Low temperatures and high rainfall always produce tropical rainforests.
• B. Temperature has no effect on the type of forest; only rainfall matters.
• C. Forests only develop in areas with low rainfall, regardless of temperature.
• D. High temperatures and high rainfall typically result in tropical rainforests, while lower temperatures and moderate rainfall support temperate forests.

Answer: (D)

Verified step by step guidance

1. Step 1: Understand the concept of biomes. Biomes are large ecological areas defined by specific climate conditions, including temperature and rainfall, which influence the types of vegetation and animal life that thrive there.
2. Step 2: Recognize the relationship between temperature and rainfall in determining forest biomes. High temperatures and high rainfall typically support tropical rainforests, which are characterized by dense vegetation and high biodiversity.
3. Step 3: Identify how lower temperatures and moderate rainfall influence forest biomes. These conditions typically support temperate forests, which have distinct seasons and a mix of deciduous and evergreen trees.
4. Step 4: Eliminate incorrect statements. For example, 'Low temperatures and high rainfall always produce tropical rainforests' is incorrect because tropical rainforests require high temperatures. Similarly, 'Temperature has no effect on the type of forest; only rainfall matters' is incorrect because temperature is a critical factor in biome development.
5. Step 5: Conclude that the correct description is: High temperatures and high rainfall typically result in tropical rainforests, while lower temperatures and moderate rainfall support temperate forests. This aligns with the interplay of climate factors in shaping forest biomes.
