Climb through a rainforest from the dark, damp floor all the way up to the sunny treetops. Meet the four layers and the animals that call each one home — and find out what makes every level special.
What you’ll learn
- A Forest in LayersUnderstand that a rainforest grows in four layers set by how much sunlight reaches each.A rainforest is built in four stacked layers, from the sunny treetops down to the dark floor. Sunlight decreases as you go down, and that changing light is what makes each layer a different home for plants and animals.
- The Emergent LayerDescribe the sunny emergent layer and the animals that live there.The emergent layer is made of a few super-tall trees that rise above the rest, reaching the most sunlight but also strong winds. Big flying animals like the harpy eagle, plus bats and butterflies, live in this top layer.
- The CanopyExplain that the canopy is the leafy roof where most rainforest animals live.The canopy is the dense green roof of the forest that catches most of the sunlight and rain. It holds plenty of fruit and flowers, so it is home to more animals — monkeys, sloths, toucans, and parrots — than any other layer.
- The UnderstoryDescribe the shady understory and how its plants and animals adapt to low light.The understory sits below the canopy in deep shade, receiving only a small share of the sunlight. Plants grow large leaves to catch what light they can, and many small creatures — frogs, insects, and lizards — shelter here.
- The Forest FloorExplain that the dark, damp forest floor receives very little sunlight and is home to decomposers.The forest floor is the darkest, dampest layer, receiving only about 2% of the sunlight that hits the treetops. Its clean-up crew — ants, worms, and fungi — breaks down fallen leaves and returns nutrients to the soil.
- Why Layers MatterConnect decreasing sunlight to where different plants and animals live in the forest.Sunlight weakens from the treetops to the floor, so each layer becomes a distinct home. Animals and plants live where their light and food are found, which is why the four layers together make one rich, working forest.
Questions this course answers
What makes the layers of the rainforest different from each other?
Sunlight is the secret! There is lots of light at the top and very little at the bottom, so each layer becomes a different home.
The emergent layer is at the top. What is it like up there?
The emergent treetops poke into the open sky, so they are the sunniest and windiest part of the forest.
Where do MOST rainforest animals live?
The canopy is the busiest layer, with lots of sunlight and fruit, so more animals live there than anywhere else.
Why do understory plants grow such big leaves?
The canopy blocks most of the sun, so understory plants grow big leaves to catch every sunbeam they can.
Out of 100 sunbeams hitting the treetops, about how many reach the forest floor?
Only about 2 out of 100 sunbeams make it to the floor — the leaves above catch almost all the rest, so it is very dark.
Which animal would you find on the forest floor?
Worms live in the damp soil of the dark forest floor. Eagles, toucans, and monkeys all live up high in the trees.
