Explanation: Indonesia and Malaysia lie on the equator with year-round heat and rain.

• A. Frontal rain
• B. Orographic rain only

• D. Saplings

Explanation: Emergent trees tower above the canopy into full sunlight.

• A. They filter ocean water
• B. They breathe like animals
• C. They are shaped like lungs
• D. They absorb large amounts of carbon dioxide and release oxygen

Explanation: Rainforest photosynthesis absorbs CO₂ and releases oxygen on a vast scale.
