Tropical Rainforest By: Usama Ahmad
Where are they? Enchanted Learning, 2012
Some animals … The jaguar has adapted to the rainforest for it is a nocturnal animal, meaning that its prey cannot escape. It is also has a muscular and stocky body due to evolution. Jaguars can also swim due to adaptation. The toucan has adapted to the rainforest for it has a colourful beak for attracting mates, a narrow tongue like a feather for reaching small places and saw-like edges on their beaks for shredding fruits. The poison dart frog has adapted to the rainforest for it is very small so its predators can’t spot it, its coloured in special colours for camouflage and the frogs skin can expel poison. American School of Lima, 2012 Caltech, 2012 Tropical Rainforest Animals, 2012
Some plants … The pitcher plant has adapted to the rainforest for it has downward-pointing hairs to trap insects who get stuck inside, it has a special secretion that is appealing to insects and because it grows in nutrient-poor places, it has adapted to be a carnivore. Strangler figs have adapted to the rainforest for they grow from seeds that birds excrete on tree branches, then they grow roots to steal the trees water and nutrients and finally, it grows up to block the trees light. Trees have adapted to the rainforest for they have buttress, or prop roots to keep them up in the poor, soft soil, they have leaves with a big surface area for absorbing moisture and they have smooth bark to stop other organisms from growing on it.

Abiotic factors Average Temperature: 20 to 34 ℃ Annual Rainfall: More than 250 cm Average Humidity: 77 to 88% Soil Erosion: The soil rapidly erodes when exposed to rain after the vegetation is removed. This also causes floods as the soil is deposited on river beds. Tropical Rainforest, 2012
Resources Some important resources we get from the rainforest are: • Food • Avocados • Guava • Okra • Medicine • Curare (muscle relaxant) • Quinine (Anti-malaria treatment) • Everyday things • Paper • Rubber • Oil Smithsonian Centre, 2012
How did science help us find these cure? About 2,100 of 3,000 plants that help cure cancer come from the rainforest. Most medicines were discovered by medicine men and then, scientists confirmed the medicines. Some other examples include: • Quinine, used in the treatment of malaria, comes from the bark of the cinchona tree • Alkaline D-Turbocuarine, which helps in treating muscular disorders, comes from the bark of curare lianas (woody plants that hang from trees) • In Madagascar, the rosy periwinkle contains 2 anti-tumor agents, one offers a 99% chance of recovery from leukemia, and one offers a 58% chance of recovery from Hodgkin’s Disease.

How humans affect the rainforest • Deforestation Every year, about 78 million acres of wood are cut down. People are cutting down trees for paper, wood, housing, etc; These trees turn carbon dioxide into oxygen at a rate of 27 tons per acre every year! • Cattle ranching This is a MAJOR cause of deforestation. Since 1950, 2⁄3 of lowland tropical forests have turned into cattle ranches! Internet Geography, 2012
The Effect • Money The use of these resources affects money because people are paid to do research on new medicines, people are paid to cut down wood, etc; • Health The use of these resources affects health for we can find new cures for diseases. Trees also make most of Earth’s oxygen and rainforests are full of trees. • Environment The use of these resources affects environments because when we cut down trees, we’re cutting down something that both plants and animals rely on to live because they get food and shelter in trees. Trees are also very important as they balance out the amount of carbon dioxide we make every day with the amount of oxygen they make, so if we had less trees, we would have more global warming.
