LAYERS OF A RAINFOREST
EMERGENT LAYER
The tallest trees are the emergent's, towering as
much as 200 feet above the forest floor with trunks
that measure up to 16 feet around. Most of these
trees are broad-leaved, hardwood evergreens.
Sunlight is plentiful up here. Animals found are
eagles, monkeys, bats and butterflies.
CANOPY LAYER
This is the primary layer of the forest and forms a
roof over the two remaining layers. Most canopy
trees have smooth, oval leaves that come to a point.
It's a maze of leaves and branches. Many animals
live in this area since food is abundant. Those
animals include: snakes, toucans and tree frogs.
UNDERSTORY LAYER
Little sunshine reaches this area so the plants have
to grow larger leaves to reach the sunlight. The
plants in this area seldom grow to 12 feet. Many
animals live here including jaguars, red-eyed tree
frogs and leopards. There is a large concentration of
insects here.
FOREST FLOOR
It's very dark down here. Almost no plants grow in
this area, as a result. Since hardly any sun reaches
the forest floor things begin to decay quickly. A leaf
that might take one year to decompose in a regular
climate will disappear in 6 weeks. Giant anteaters
live in this layer.
