What adaptations do plants in rainforests have that helps rainwater fall off of them
Drip tip
Why are drip tips important
If too much water builds up on a leaf leading to damage( this limits the amount of photosynthesis providing energy to the plant meaning it can’t grow)
What is the name of the roots of trees in the emergent/canopy layer( kapok trees7
Buttress roots
Why are buttress roots so important
They help keep tall trees such as kapok trees to stay up in the high winds
Why do plants in the canopy/ emergent layer have small leaves
to retain water
Why do plants on the forest floor have large leaves
So they can absorb more sunlight to photosynthesis
How much sunlight reaches the forest floor
2%

What are the reasons for deforestation in Malaysia
- commercial farming ( e.g. palm oil, live stock,etc )
- logging ( provide wood supply )
