Tropical Rainforest AQA Geog GCSE CGP P25 Adaptions

In order to survive, many animals and plants have adapted to the physical conditions of their surroundings. In the rainforest these include:

• the competition for light

• high rainfall

• All of these are correct

Match the following

• Trees compete for sunlight

• which helps to repel the rain

• Plants have thick waxy leaves

• by growing tall

• Plants drop their leaves throughout the year

What is the job of the buttress root?

• To give animals shelter from the rain

• To support the tree from strong winds

• To allow animals to climb up the trees

• To create places for animals to build dens

What are the advantages of thick waxy leaves with drip-tips?

• Waxy leaves channel the water to the point so encouraging runoff

• As rain runs off waxy leaves the weight of water does not damage the leaf

• Water is not allowed to pool on the leaves so fungi and bacteria cannot grow

• All of these are correct

• winds

Reorder the following starting at ground level (1)

​ (a)   trees only have branches at their crown, where most ​ (b)   is available.

• Emergent
• light
• Main canopy
• Shrub
• air
