​Climate graph

​- broad-leaved evergreen plants

-glossy,waxy skin

-​drip tip

​Vegetation

​- they grow on trees

-get water from the air​

e.g.orchids, bromeliads​

​​Epiphytes

​

​​Plants with drip tip

​

​They climb up on trees to get light!

e.g. lianas​

​

​​Creepers

​Layers of tropical rrainforests

​The forest floor is the darkest of all rainforest layers, making it extremely difficult for plants to grow.

​

​Forest floor

​This soil is acidic and poor in nutrients.

​The humus layer is quickly washed out. Most nutrients are absorbed by the plants and do not get into the soil at all.

Decomposition is very fast because of warm and humid weather.​
