Tropical Rainforest
Background
The tropical rainforest is the most biodiverse and productive biome on our planet
but the most fragile. They are the most productive biome with a net primary
production of 2,200 g/m^2/year.
Rainforests cover only 6 % of the Earth's surface but yet they contain more than 1/2…

INTER-TROPICAL Climate
CONVERGENCE ZONE
This is a result of the
heating of part of the Tropical Rainforests have distinctive climates.
Earth's surface, caused by the concentrated insolation from the overhead sun Hot and wet year round ­

increased surface runoff and often flooding.
Dec & Jan: ITCZ movement results in higher air pressure and lower rainfall, same in
July.
Soil moisture utilisation occurs as evaporation and transpiration exceed precipitation-
dry season is short so no soil moisture deficit.

Adaptations
As many as 30 million species of plants and animals live in tropical rainforests. They
have the highest biodiversity and are believed to contain half the worlds gene pool.
Plants (Flora)
Plants are adapted to the heavy rainfall - they have thick, waxy leaves with pointed tips
(called drip-tips).…
