The Amazon is the world's largest tropical rainforest. It is roughly the
size of the continent of Australia and covers an area of nearly 2.8 million
square miles. The Amazon rainforest gets its life from the majestic
Amazon River which runs through the heart of the region Amazon is
also the second largest river in the world. The rainforest is simply the
drainage basin for the river and its tributaries. The vast forest consists of
four layers, cach featuring its own ecosystems and specially adapted
plants and animals.
The forest floor is the lowest region. Since only two perecnt of the
sunlight can filter through the top layers to the understory very few
plants grow there. The forest floor, however, is rich with rotting
vegetation and bodies of dead animals which quickly break down and get
integrated into the soil as nutrients. Tree roots stay close to these
available nutrients and decomposers such as millipedes and earth worms
use these nutrients for food.
The understory is the layer above the forest floor. Much like the forest
floor, only about 2 to 5 percent of the sunlight reaches this shadowy
realm. Many of the plants in the understory have large, broad leaves to
collect as much sunlight as possible. The understory is so thick that there
is very little air movement. As a result, plants rely on insects and animals
to pollinate their flowers,
The layer above the understory is the canopy. This is where much of the
action in the rainforest occurs. Many plants growing in this layer have
specially adapted leaves with drip tips Drip tips allow water to flow ofl
the leaves and thus prevent mosses, fungi and lichens from infecting the
leaves. Leaves in the canopy are very dense and filter about 80 percent of
the sunlight. The canopy is where the wealth of the rainforest's fruits and
flowers grow
