Title: Rainforest

Rainforest
  • By Doran Logsdon

Rainforests
  • Rainforests are very dense,warm, wet forests that
    are havens for millions of plants and animals.The
    plants in the rainforest generate much of Earths
    oxygen. But that is not the only use of these
    plants, some are used to make new drugs that
    fight disease and illness.

3
Where are rainforests?
  • Tropical rainforests are located in a band around
    the equator, mostly in the area between the
    Tropic of Cancer (23.5N Latitude) and the Tropic
    of Capricorn (23.5S Latitude). This 3,000 mile
    wide band is called the Tropics. Tropical
    rainforests are found in South America, West
    Africa, Australia, Southern India, and Southeast
    Asia.

4
Animal Life
  • Many species of animal life can be found in the
    rainforest. Most species have one common
    characteristic, that they adapt to life in
    trees.
  • Insects make up the largest single group of
    animals that live in the tropical rainforests.
    They include butterflies, mosquitoes, stick
    insects, and huge colonies of ants.

5
Plant life
  • Plant lie on the forest floor receive 3 of the
    light the light that filters through the the
    canopy..

6
Layers of the rainforest
  • There are four very distinct layers of trees in
    a tropical rain forest. These layers have been
    identified as the emergent, upper canopy,
    understory, and the forest floor. Emergent trees
    are spaced wide apart and are 100 to 240 feet
    tall with umbrella shaped canopies that grow
    above the forest. The upper canopy of 60 to 130
    foot trees allow light to be easily available at
    the top. The understory consists of 60 foot
    trees. The forest floor is usually completely
    shaded, except where trees have fallen and light
    shines through.

7
Deforestation
  • About 2,000 trees per minute are being cut down
    in the rainforest. If this keeps up many animals
    and plants will become extinct.

8
Some random facts
  • Giant bamboo plants can grow up to 9 inches a
    day.
  • The trees of a tropical rainforest are so
    densely packed that rain falling on the canopy
    can take as long as 10 minutes to reach the
    ground.
  • In the moist rainforests of South America, Sloths
    move so slowly that algae are able to grow in
    their fur.

9
Conclusion
  • If we keep destroying our rainforest we will lose
    hundreds of plant species and animals alike.
