The Amazon is the world's largest tropical rainforest. It covers an area of nearly 2.8
million square miles, which is nearly the size of the continent of Australia. The
Amazon Rainforest gets its life from the majestic Amazon River, the world's
second largest river, which runs directly through the heart of the region. The
rainforest itself is simply the drainage basin for the river and its many tributaries.
The vast forest itself consists of four layers, each featuring its own ecosystems
and specially adapted plants and animals.
The forest floor is the lowest region. Since only two percent of the sunlight filters
through the top layers to the understory, very few plants grow here. The forest
floor, however, is rich with rotting vegetation and the bodies of dead organisms,
which are quickly broken down into nutrients integrated into the soil. Tree roots
stay close to these available nutrients and decomposers, such as millipedes and
earthworms, use these nutrients for food.
The understory is the layer above the forest floor. Much like the forest floor, only
about 2- 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 canopy leaves have specially adapted leaves which
form "drip tips". Drip tips allow water to flow off the leaves which prevents
mosses, fungi, and lichens from occupying 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. Bromeliads, cup-like plants,
provide drinking pools for animals and breeding locations for tree frogs.
The emergent layer is above the canopy, and is the top layer of the rainforest.
Trees in the emergent layer break through the canopy and may reach heights of
200 feet. Leaves in the emergent layer are small and covered with a special wax to
hold water. Seeds are blown to other parts of the forest. Trees which rise to the
emergent layer are massive. Many are braced by huge buttress roots. Trunks can
be 16 feet in circumference. Many animals that survive in the emergent layer never
touch the ground.
