What you need to know
- Tropical rainforests grow near the equator, where it is hot all year and rain falls in most months.
- The forest has four layers: forest floor, understorey, canopy and emergent layer.
- The canopy absorbs over 90% of the light, so only about 2% reaches the dark forest floor and few plants grow there.
- Leaf litter rots quickly and heavy rain leaches nutrients away, so the soil is poor even though the forest above is so rich.
- Emergent trees can reach 70 m and must cope with strong sun and wind.
