Title: Rainforest

Rainforest Facts
  • Rainforests only cover 2 of the world but the
    rainforests hold 50 of the worlds trees.
  • Over one quarter of natural medicines are
    discovered in the tropical rainforest also known
    as jewels of the Earth.
  • The rainforests are responsible of 28 of the
    worlds air.

Rainforests Layers
  • The forest floor.
  • The bottom-most layer, receives only 2 of the
    sunlight. Many forms of fungi growing here help
    decay the animal and plant waste

Rainforests Layers
  • Understory Layer
  • The understory layer lies between the canopy and
    the forest floor. The understory is home to a
    number of birds, snakes and lizards, as well as
    predators such as jaguars , boa and leopards.
    Only about 5 of the sunlight shining on the
    rainforest canopy reaches the understory. This
    layer can be called a shrub layer, although the
    shrub layer may also be considered a separate
    layer.

Rainforest Layers
  • The Canopy Layer
  • The Canopy layer contains the majority of the
    largest trees, typically 3045 m tall. The canopy
    is home to 50 percent of all plant species,
    suggesting that perhaps half of all life on Earth
    could be found there. A quarter of all insect
    species are believed to exist in the rainforest
    canopy.

6
Rainforests Layers
  • The Emergent Layer
  • The emergent layer contains a small number of
    very large trees called emergents. They need to
    be able to adapt to the hot temperatures and
    strong winds that occur above the canopy in some
    areas.

Tree Frogs
  • Tree Frogs

A tree frog is spends a major portion of its
lifespan in trees. Many tree frogs can change
their colour for better camouflage. Tree frogs
are usually tiny, as their weight has to be
carried by the branches and twigs of the
rainforest.
8
Spider Monkeys
  • The spider monkey has long limbs and long tails.
  • Spider monkeys live in the upper layers of the
    rainforest
  • A spider monkeys diet is fruits and the
    occasional plants and insects

9
Bromeliads
  • Bromeliads are related to the pineapple family.
    Some bromeliads can hold several gallons of
    water. They also provide homes for wildlife in
    the rainforest.

10
Lianas

  • Ninety per cent of the world's vine species grow
    in tropical rainforests. Lianas are a type of
    climbing vine found throughout tropical
    rainforests. They have thick, woody stems and
    come in various lengths (up to 3,000 ft) and
    varying shapes. They begin life on the forest
    floor but depend on trees for support as they
    climb upwards towards the sunlight they need for
    survival.

11
The Huli Tribe Facts
  • The Huli Tribe live in Papua New Guinea.
  • The population of the Huli tribe is 150,000
  • The have lived in their current area for 1000
    years
  • They usually speak Huli and Tok Pisin.

Conclusion
  • I have learnt many things about the rainforest
    and I hope you have to!!!!!
