Temperate broadleaf forests & temperate grasslands tend to have similar annual _____________.
However, temperate broadleaf forests can support denser vegetation as they experience more ______________.

• A. Temperature; precipitation.
• B. Precipitation; disturbances.
• C. Temperature; disturbances.
• D. Precipitation; biodiversity.

Answer: (A)

Verified step by step guidance

1. Understand the characteristics of temperate broadleaf forests and temperate grasslands. Both biomes are found in temperate regions and experience similar temperature ranges, which is why 'Temperature' is a common factor.
2. Consider the factors that allow temperate broadleaf forests to support denser vegetation compared to temperate grasslands. Denser vegetation typically requires more water, so 'precipitation' is a key factor.
3. Evaluate the options given: 'Temperature; precipitation' suggests that both biomes have similar temperatures, but forests have more precipitation, which supports denser vegetation.
4. Analyze the other options: 'Precipitation; disturbances' and 'Temperature; disturbances' do not align with the need for more water to support denser vegetation.
5. Conclude that the correct answer is 'Temperature; precipitation' because it logically explains the similarities and differences in vegetation density between the two biomes.
