What is the environment of tropical forests compared to savannas?

• A. Tropical forests are arid with sparse trees.
• B. Tropical forests are humid with closely spaced trees, while savannas are drier with trees spaced further apart.
• C. Savannas are humid with dense canopy.
• D. Tropical forests have no trees.

Answer: (B)

Differences in climate drive vegetation structure. Tropical forests are hot and very humid with abundant, year‑round rainfall, supporting a dense, multi‑layered canopy where trees grow close together and shade the understory. Savannas, by contrast, are drier with a longer dry season, so trees are spaced far apart and grasses dominate the ground. This combination—humid and densely treed versus drier with widely spaced trees—best matches the described contrast.
