Transcript of tropical Rainforest
A Tropical Rainforest is a forest with tall trees, and a year-round temperature of 94 degrees and never falls below 64 degrees. Also it recieves 250 cm of rainfall each year, 21.3 cm each month.
In this presentation we are going to explain the biomes in a Tropical Rainforest by showing what the species that live there are.
Plants found in the Tropical Rainforest biome.
Animals found in the Tropical Rainforest Biome
Africa Forest Elephant
Look different than Savanna Elephant
Smaller and Stockier
Male Forest Elephants only get about 8 feet tall
Their ivory tusks have a pinkish tinge
Have a long narrow face because their lower jaw is longer
Have adapted to live in dense forests
They are smaller, which makes them capable of moving through the forest easier
Their tusks go out straight instead of curved so as to not get caught in the under brush
Not much is known about them because they are harder to track than regular elephants
They are placed on the endangered species list
Tropical Rainforest Food Chain
Tropical Rainforest Map
Bengal Bamboo is found in southeast Asia.
It will grow to a height of 40-80 ft.
Bengal Bamboo has thin, long, green leaves and dark green stems with chambers inside them.
Will have flowers once in its lifetime, which die after they bloom. It does not matter where the flowers are they all look the same.
Bengal Bamboo is in fact not a tree or bush, but actually is a grass.
It helps stop soil erosion.
Sucks up extra water that falls during the many rain showers, that would have drown most of the other plants in the area
Provides homes for many animals.
Bengal Bamboo will grow very tall very fast so it gets all the sunlight.

Spineless Indian Bamboo, Calcutta Cane
Tropical Rainforests in South America, particularly Brazil, Bolivia, Peru, Ecuador, Columbia, and Venezuela.
Can grow to be 30 ft tall.
Bougainvillea can be vines, trees, or even shrubs with very pointy thorns.
The flowers can be a variety of colors: from red, to white, to yellow, to pink, to orange, or even purple.
The flowers are made up of small tubes surrounded by thin papery flowers.
The Bougainvillea has drip tips at the end of its heart-shaped leaves, so it is not weighed down by a heavy rainfall.
Leaves are a dark rich green color that clearly resembles ivy.
The leaves also have fine hairs on their undersides.
Developed hooks so it could climb other plants for support.
Can grow in semi or complete sunlight.
Sundanese regions of India, Bangladesh, China, Siberia, and Indonesia
The color base is an orangish brown with white accents around its cheek, mouth, eyebrows, and stomach. Long black stripes complete the tigers look
Can weigh up to 575 pounds
The build of the Bengal Tiger is broad with long lean legs that are slender
Most of the time, the texture of the fur is very fine and feels soft to the touch
This particular tiger is very quiet and can be quite sneaky
The Bengal Tiger is not the largest tiger, the largest happens to be its cousin, the Siberian Tiger
Bengal Tigers can get up to ten feet long and three feet tall
The average life span for a wild tiger is around 15 years
The Bengal Tiger is a carnivore, it eats; boars, wild ox, monkeys, and other animals
It can catch bigger animals but prefers to catch the young of the old because they don't run as fast
Is placed on the endangered species list

leaves are smooth on top and hairy on bottom with deeply indented veins that run the length of the leaves.
small clusters on greenish-white flowers appear all over the plant. Flowers are both male and female.
has tiny fleshy oval-shaped fruits about 1-2 mm long.
tribes and locals will use the roots and stems of the curare, along with various other plants and venomous animals, to create a poison that causes paralysis in the upper body that often leads to death if it gets into the bloodstream.

All have a bunch of light feathery leaves at the top of their smooth and graceful trunks.
The trunks are a light gray color, while the leaves are a greenish yellow color.
The coconut tree will flower clusters of flowers, which will develop into the coconut fruit, otherwise known as the coconut.
The coconut has a hard outer shell, a soft meaty inner layer, and a hollow center filled with coconut milk.

Linn's Sloth looks fatter than what it actually is for it has an extra layer of skin
Arms are long and have two small claws at the end of their hands used for defense, that is why they are called the two-toed sloth
Life span: 27-32 years
The two claws on its front paws help the sloth defend itself
The sloths fur has adapted so that the sloth blends in easily; also allows algae to help blend in

They shed most to all of their leaves during the tropical dry season
The leaves are palmate and compound
7-8 cm. long and 1-3.5cm. wide
Flowers usually open before the leaf appears
Flower has five pedals which are each about 2.5 cm. long
The trees are used to make dugout canoes
Widely spread around the world and occupies an important niche in the rainforest biome
In all of the main rainforests.
The strangler fig is one of the most important plant s in the rainforests, and there are over 1,000 different species of it.
A few times a year the figs contain fruit and that explains why they are so important to the animals of the rainforests.
70% of animals in the rainforests eat the strangler figs.
Strangler Figs can grow up to 148 feet.The strangler figs tree has waxy leaves that protect it from the dry winds and sunlight.
The strangler fig has a very extraordinary kind of flower, it actually has a male flower that contains pollen, and a female flower that contains seeds.
There are two different types of female flowers, one has a short style, and the other has a long style.
There are many ways that human activity is harming the rainforests, and one of the main ones are that we are cutting down the trees to make room for our wants and needs.
Ways we are cutting down trees:
- Cuts down trees for building and other things.
Power Plants & Industries
- Cut and burn trees for electricity.
- Use slash and burn to make room for crops.
- Flood areas of the rainforests.
Picture of the trees that were burned and cut down.
Southeast Asian tropical rainforest of Sumatra and Borneo
They spend most of their life-time in the tree tops and descend very rarely
Largest tree dwelling ape in Southeast Asia

Females can weigh up to 110 pounds
Their arms are large and lanky, having a span of eight feet across when full grown. Their legs, though, are short and usually very weak
Long, thin red fur
Their Big toes are much like our thumbs; they are able to rotate and touch the ends of the other toes
Their adaptations are their strong arms for swinging from tree to tree and their curved feet with the "foot thumb" to be able to balance and grab the branches that they are standing upon
Can live up to 45 years in the wild and 50 in captivity
Is an omnivore
Javan or Moloch Gibbon, Owa, Wauwau
Scattered remains of the Java Rainforest
The female Gibbon sings a song several times in a day to indicate where her territory is located. The song is made up of a specific set of notes held for certain lengths of time; Starts off with a soft short note, then a series of eight short notes, followed by two longer notes which changes into two soaring notes, the song then ends with two shorter notes, a series of eight short notes and then a single last soft note. Only the females sings this song
the territory is stable and usually about 42 acres
If the male spots any strangers while the song is being sung, he chases them of with a single constant screeching noise
Small apes, no tail, and weigh about 13 pounds
Their bodies have adapted; long fingers and arms and lean bodies for swinging from tree to tree
Both males and females are light grey to white in color and grey to a black covering on their heads
Put on the red list of endangered species
they are very carefully watch (population wise) 50% chance or better of going endangered
They are omnivores, they will eat meat if fruit is scarce
Near endangered Animals:
Chimpanzee, Bengal Tiger
Critically Endangered Animals:
Orangutan, Silvery Gibbon
Durians and Mangroves
Where rainforest meet ocean; all around the world
Live on the edge of where the rainforest meets the ocean
Grow where other plants cannot
They protect coast lines and prevent erosion
Mangroves actually look like they grow on stilts
The stilt like object happens to be their roots, which are thin and grow up out of the water
Mangrove stores the salt from the salt water into its leaves, which it then later sheds to dispose of said salt
The seeds of the mangrove are tough and able to float
It is believed that the seed has originated from Southeast Asia and has slowly made its way around the world throught he ocean
One of the most biologically diverse forests
One of the most threatened habitats in the world
Mengaris, Honey Bee Tree, Deoh
Can each the height of 250 feet
that is the equivilant of a 30 story building
Perfer damp locations; near rivers, in vallies, and the lower slopes of hills
Tualang trees are part of the legume family and are related to the peas
Their leaves are pinnate
4-5 leaflets growing along a central rib
The seeds are contained within large pods much like the peas
The trunks of the trees are covered in a smoth, silvery bark that is very slippery and discourages sun bears from climbing up the tall tree
the Sun Bear climbs the tree to try to reach the honey combs of the Asian rock bees
Branches start to grow at 100 feet up the trunk of the tree
The sap that the tree forms is irritating to human skin and forms a rash ofter contact
The combs that the bees for on the tree grow up to 6 feet across
People who live near and harvist the honey cherish and protect the trees
Open areas, lowland rainforests, and palm groves of South America

Live in flocks
Toco Toucan is a preditor but it also eats fruits and nuts, making it an omnivore
Tropical and subtropical areas of South America
Looks Like pig with largre pointy ears, fangs, and wings
About three inches in length with a wing span of eight inches. Weighs about one ounce
The bat is equipt with a clawed thumb that comes out of the front edge of the wing
It uses this thumb to climb around on its prey
It has a very short dark grey coat
Only has two point fangs in the front of its mouth
It has special saliva that runs in the groves of its tongue to stop the blood from clotting
It is a preditor and a prey. Its prey are eagles and hawks
lives in Mangrove Forests
Climate change effects the rainforest in more way than you think was possible. Clouds are forming high above tree tops, which results in slightly less rainfall in the year. Plants are not taking in as much carbin dioxide as they used to, in fact, they emmit more carbon dioxide than they take in, which also leads to different weather climates
Because there is rainfall year round, the soil gets stripped of many of its nutrients
Though even the clay has been stripped from and has been replaced by aluminum oxide
The land that rainforests' usualy cover are quite rocky. It is not uncommon that the rainforest covers mountains and hills as well.
Average yearly precipitation:
lies between 175 cm. (69 inches) and 250 cm. (99inches)
Average yearly temperature:
It lies between 68 degrees F (20 degrees C) and 93 degrees F (34 degrees C)
Rainforests are believed to be the oldest and most complex land-based ecosystem on earth today. The rainforests contain over 30 million different species of plants and animals. Rainfoest have many medical plants include in it biodiversity that people use on a daily basis. Many of the foods that we consume daily are known to grow within the rainforest. The rainforest provides himes, medical supplies, food and much more.
