EMERGENTS: Giant trees that are much higher than the average canopy height. It houses many birds and insects.

CANOPY: The upper parts of the trees. This leafy environment is full of life in a tropical rainforest and includes: insects, birds, reptiles, mammals, and more.

UNDERSTORY: A dark, cool environment under the leaves but over the ground.

FOREST FLOOR: Teeming with animal life, especially insects. The largest animals in the rainforest generally live here.

Emergent Level

-Emergent layer of the rainforest is a layer of trees stretching 50 to 60 meters above the forest floor.

Page 4: Tropical Rainforest

Canopy

-This layer supports most of the rainforest animals.

-The canopy offers such an abundance of shelter that many of the animals living in this layer never need to descend from it.

-Insects hum and nibble on plants, reptiles slither along the branches and trunks of trees, monkeys chatter back and forth as they swing through the branches, and brightly colored birds dart among leaves.

Understory

- Made up of the trunks of canopy trees, shrubs, plants and smaller trees.

- Many of the plants living in this level have adapted to growing in the shade and don't need much light.

Tropical Rain Forests

• Tropical rain forests are found in a belt around the equator, where temperatures and rainfall are very high all year round

• There is very little variation between the seasons• They will have an even distribution of rainfall annually• Warm temperatures with less variation during the year• The best known rain forests are found in tropical regions

between the Tropics of cancer and Capricorn

The Amazon Rainforest

• One of the most well known rainforests is the Amazon

• Where is the Amazon?• South America• The Amazon rainforest is the largest rainforest in

the world• It covers an area about two thirds the size of the

US• Two thirds of the Earth’s fresh water can be

found there

-In the Rainforest they live at the top of the tallest trees, which is in the Emergent layer (emergent layer is high-up above the canopy.)

- The Blue Morpho has blue wings with a brown border.

-The Blue Morpho’s colors blend in it’s surroundings.

Where are tropical rainforests located?

Tropical rainforests are located close to the Equator between theTropic of Cancer and the Tropic of Capricorn. This means that it isalways hot – between 70 and 85o F.

THE FOREST FLOOR

Very little sunlight reaches the forest floor so few plants can grow.However, there are thousands of species of insects such as ants, beetlesand termites crawling around. This agouti paca lives on the forest flooralong with other animals such as jaguars, anteaters and snakes.

Why are rainforests so important?

Rainforests are home to more than half of the world’s plant andanimal species. Some animals can only be found in the rainforest

Page 21: Tropical Rainforest

The rainforest plays a big role in the Earth’s climate!

Trees use carbon dioxide and provide oxygen – just the opposite ofpeople. By using a lot of carbon dioxide each day, rainforests keep thetemperature, humidity, rainfall and wind levels of the Earth stable. Ifthere is too much carbon dioxide, those things might change

MedicinesThere’s a reason why rainforests are called the “world’s largestpharmacies”! We have already developed medicines such as thoseused to fight cancer, diabetes and heart diseases from rainforest plants.More cures might be found here one day!

Bark from the Cinchona tree has been used to produce Quinine, a drugused to prevent and treat malaria. Cinchona comes from South America.

Do you eat bananas? Do you know someone whodrinks coffee? Do you use anything made of wood?

All of these things originated in the rainforest!

Why are rainforests disappearing?

It is hard to balance the needs of people and the protection of rainforests.With the world’s population growing every day, there is more and morepressure on forests. Many rainforests are cut down for land to live on orto create products that we all need, such as beef or paper. But wait – wecan still have our rainforest and eat our chocolate, too.

By asking your parents to choose products that are made in away that is safe for the forest and for people, you can help savethe rainforest -- and all the plants and animals we depend on andlove.
