The Beautiful Rainforest

• The rainforest is beautiful and an amazing place
  to visit. There are many species of plant and
  animals. The rainforest is a very fascinating and
  interesting place to visit. Unfortunately our
  beautiful rainforest is being cut down. The
  rainforest is covered with things people didnt
  discover and can provide us with cures for
  cancers. Nearly 50 percent of our animals rely
  on our rainforest to provide them homes and food.
  Read on to find out more!!!

The rainforest

• Rainforests are one of our Earths beautiful
  treasures. Rainforests are found in the tropics,
  near the equator. In this region the sun is very
  strong and shines about every day all year long
  making the climate warm and stable. The average
  temperature is 2 0 degrees 24 degrees celsius.
• Although the rainforest only covers 2 of our
  Earths surface they are homes of about 50
  percent of the plants and animals of our Earth.
  Rain forests receive at least 80 inches of rain
  per year.
• DID YOU KNOW!!!!!!
• Americans use 50 million tons of paper per year,
  consuming more than 850 million trees. Everyday
  about 50 100 species of animals and plants
  become extinct.

Where are Rainforests Found?

• Although the rainforest only covers 2 of our
  Earths surface they are homes of about 50
  percent of the plants and animals of our Earth.
  Rain forests receive at least 80 inches of rain
  per year.
• Brazil, Indonesia, Peru, Indonesia, Bolivia,
  Mexico and India are the countries with the
  largest amount of rain forests.
• Rain forests are interesting places to visit.
  They protect us against floods droughts and
  erosion. They are homes to lots of species of
  plants and animals.

The biotic and abiotic factors of the rainforest

• Abiotic factors are parts of the nrainforest that
  is not alive. Biotic factors are parts of the
  rainforest that are alive.
• The abiotic factors are sunlight, climate,
  weather and precipitation. The abiotic factors
  are very important because if not enough of these
  the plants and animals can die. The Biotic
  factors are plants, animals both hervibore and
  carnivore and insects.
• With too much of one biotic factor the others
  will be affected.

Native Plants

• There are over 20,000 known species and orchids
  are especially common in moist tropical regions.
  Although temperate orchids usually grow in the
  soil, tropical orchids are more often epiphytes
  which grow on trees.
• Bromeliads are related to the pineapple family.
  Their thick, waxy leaves form a bowl shape in the
  centre for catching rainwater. Some bromeliads
  can hold several gallons of water and are
  miniature ecosystems in themselves providing
  homes for several creatures including frogs and
  their tadpoles, salamanders, snails, beetles and
  mosquito larvae. Those that die decompose and
  furnish the plant with nutrients. One bromeliad
  was found to contain several small beetles, crane
  flies, earwigs, a frog, a cockroach, spiders, fly
  larvae, a millipede, a scorpion, woodlice and an
  earthworm!
• Most rainforest soil is very poor with all the
  nutrients available largely remaining at surface
  level. Because of this rainforest trees have very
  shallow roots. Some very tall trees have
  developed ways of obtaining much needed
  additional support by forming buttressed roots,
  which grow out from the base of the trunk
  sometimes as high as 15 ft above the ground.
  These extended roots also increase the area over
  which nutrients can be absorbed from the soil.
• Mangrove rainforest trees require a different
  kind of support system. Mangroves grow in wet,
  muddy soil at the water's edge which can be
  subject to tides and flooding. As a means of
  support they develop several aerial
  pitchfork-like extensions from the trunk which
  grow downwards and anchor themselves in the soil
  trapping sediment which helps to stabilize the
  tree.
• Saprophytes are the organisms that act as the
  rainforests decomposers, competing with the heavy
  rainfall which constantly washes away nutrients
  on the forest floors.

Native Animals

• Orangutan
• The Orangutan lives on the islands of Borneo and
  Sumatra in Indonesia. The Orangutan eats
  tropical fruit and also leaves, bark and insects
  at times
• Gorilla
• Gorillas are found in West Central Africa mostly
  in Zaire, Rwanda, and along the Congo River.
  Gorillas eat mostly leaves, fruit and bark.
• Bengal tigers
• Bengal tigers can be found in southeast Asia in
  parts of India, China, Bangladesh and Indonesia
  as well as other southeast Asian countries.
  Bengal Tigers' diets consist of antelopes, boars,
  monkeys, pigs, birds and occasionally elephants.

People that live in the Rainforest

• The native people that lived in the rainforest
  are called Penans. They are located in Borneo.
  They are nomadic which means they dont have a
  specific home. They live with what the rainforest
  provides them. They follow the blossoming sago
  palms for sago palms are their main source of
  food.

Competition of the Rainforest

• The rainforest is filled with competition and
  cooperation. Most plants compete on whos going
  to get the most sunlight because with all the
  canopies and trees not every plant gets enough
  sunlight so they try to grow taller and taller.
  Sometimes the forest floor is bare because there
  isnt enough sunlight. Getting light is only half
  the story, they also compete in whos going to
  get enough minerals in the soil, with the heavy
  rain the minerals in the soil are washed away.
• Coorperation please add.

Threats to the Rainforest

• Deforestation
• People cut down trees in the rainforest for
  supplies and land. Lets look at human population
  growth, we need more food and land. Unfortunately
  once cleared the soil loses its nutrients and
  more land is to be cleared. Also trees are needed
  for wooden supplies.
• Global Warming
• Global Warming is a problem to everyone
  including the rainforest. Global Warming is
  changing our climates. Climate change is one
  threat from Global Warming but climate change
  means changing rainfall patterns which affects
  our rainforest.
