Tropical Rainforest Introduction
- The tropical rainforest is earth's most complex biome in
terms of both structure and species diversity.
- Tropical forests, covering 7% of the
earth's surface area, contain perhaps 50% of the world's species.
- It occurs under optimal growing conditions: abundant
precipitation and year round warmth.
- There is no annual rhythm to the forest; rather each
species has evolved its own flowering and fruiting seasons.
- Sunlight is a major limiting factor. A variety of
strategies have been successful in the struggle to reach light or to adapt to
the low intensity of light beneath the canopy.
