Tropical rainforest biome
is the most complex and species-rich biome on the Earth. 80% of all
world's biodiversity is found here.
The
reason
for such amazing
number of species is the ideal
climatic
conditions for plant growth: the warmth, and, more
than anything - the
moisture.
It
rains a lot
in tropical
rainforest biome - up to 2000mm a year. The high rainfall often results
in
poor soils,
because of leaching of soluble nutrients.
This
is
compensated by extra high
productivity - things decompose about 10
times quicker in tropical rainforests than in other biomes.
Tropical
rainforests are also known for their layers
(temperate
rainforests
also
have layers even though they can be less obvious).
The canopy
layer typically blocks the sunlight, creating the dark forest floor
where the vegetation is scarce enough that we can walk on the forest
floor.
If a tree falls and opens the canopy, a myriad of small pant species
start growing on the forest
floor.
If
large parts of the canopy are opened after say, a hurricane, the
vegetation on the forest floor becomes so dense that we would not be
able to walk there - it becomes a real jungle.
The
world's tropical
rainforests
are found in a belt around equator:
* Amazon -
the world's largest tropical rainforest
* Other tropical
rainforests in Americas: Brazil's eastern coast; and
the eastern parts of all the countries in central America; and
southern Mexico
