Tropical Rainforests

2. These roots are an adaptation that provide support to the base of tall trees and help transport water. They may also help oxygen/carbon dioxide exchange by increasing the surface area (8)
6. Many leaves in the tropical rainforest have this to allow the heavy rainfall to drip off the leaf (4-3)
8. These plants can live on branches high in the canopy to seek sunlight. They obtain nutrients from water and air rather than soil. (9)
9. The very large, fast-growing trees such as the capoc that out-compete other trees to reach sunlight (9)
10. A red-coloured, infertile soil that is rich in iron and very acidic (7)
11. A type of layering in the stratification of the forest (6)
12. These grow on the roots and transfer nutrients straight from the air (5)

1. The process of breaking down of dead leaves that occurs quickly here due to the humid conditions (13)
3. A major problem facing the tropical rainforests (13)
4. The layering of the forest (14)
5. These are woody creepers rooted to the ground but carried by trees into the canopy where they have their leaves and flowers. (6)
7. The dissolving and removal of nutrients from the soil that occurs in the tropical rainforest due to the heavy rainfall (8)
