16. What relationships are there between the water, carbon cycle and the environment in the TRF?

Question 1

How much CO2 is absorbed here?

Answer 1

Absorb huge amounts of CO2 and 28% of world’s oxygen.

Question 2

How do lots of leaves aid the water cycle?

Answer 2

Rainforests allow a considerable amount of water to be returned to the atmosphere through evapotranspiration.

Question 3

How are floods mitigated by the water cycle in rainforestes

Answer 3

The canopy intercepts up to 75% of the rainfall, the other 25% is evaporated. Of this 75%, half is used by the plants and the other half either infiltrates into the ground or runs-off to the river.

Question 4

why is warm and wet climate so good for rainforests?

Answer 4

Warm and wet climate ideal for plant growth, promoting photosynthesis and respiration.

Question 5

Why is it such a big carbon sink?

Answer 5

Wood is 50% carbon so a huge carbon store and sink.

Question 6

Why is decomposition so active?

Answer 6

Decomposition is active due to climatic conditions - high temperatures and moisture availability.
