2Rainforests of the world The RainforestRainforests of the world
3Tropical rainforests are found in a belt around the Equator of the Earth. The 4800 km wide band is called the "tropics”.The largest rainforests are in the Amazon River Basin (South America), the Congo River Basin (Western Africa), and throughout much of Southeast Asia. Smaller rainforests are in the biggest continents.Tropical and temperate rainforests share characteristics: *Most roots of the trees come out at the base. * Vegetation is dense, tall and very green. Both types of rainforests are rich in plants and animal species, although the diversity is greater in the tropical rainforest.
4Climate The tropical rain forest is a very wet environment, that is why it is called “RAIN FOREST”The total rainfall for the year is between 1500 and 2500 mm.The range of temperature in a tropical rainforest is usually between 75° F and 80° F (24-27° C).The temperature in a rainforest never freezes and never gets very hot.The relative humidity is always high.At night it drops to between 20ºC - 25ºC
5Importance of the Rainforests The plants and animals of the rainforest provide us with food, fuel wood, shelter, jobs, and medicines.If there were no plants or trees producing air, life as we know could not exist.One major reason is that the plants in the forest turn carbon dioxide into clean air doing the photosynthesis, which helps us fight pollution and give us clean air to breath.
7CANOPY: The upper parts of the trees is an area full of life that includes: insects, birds, reptiles, mammals, and more.The upper canopy, is found just below the emergent trees.EMERGENTS TREES: Giant trees that are much higher than the average canopy height. Many birds and insects live there. This is the highest level of the rainforest.FOREST FLOOR: It is full of animal life, especially insects. The largest animals in the rainforest generally live here.UNDERSTORY: A dark, cool area under the leaves but over the ground. The lower canopy extends from the base of the trees to just below the upper canopy. It is the way for animals to get to the higher parts of the trees.
8Why are plants in danger ? Plants are in danger because of the rainforest deforestation.We are losing about 50,000 species per year.Experts estimate that we are losing 137 plants, species every single day due to rainforest deforestation.Bautista and Emilio
9sugarSugar Cane is grown in mainly tropical climates, but it can be found as far north as Southern Spain and as far south as Southern AustraliaSugar comes from two principal sources: Sugar Cane - a large bamboo type plant up to 5 meters and more. Sugar Beet - grown in colder climates, it looks like a turnip.The map on the left shows the main sugar cane growing regions in the world today
11The white coffee flower has five petals and a scent resembling that of jasmine. coffee berries are cherry-sized and green at first, turning dark red later on. The ripening takes eight months.The coffee tree starts flowering at 2-4 years old and it can simultaneously have flowers and berries in all stages of development. The coffee tree is a shrub with a straight trunk, which can survive for about 50 to 70 years.
13Rubber Trees By: Chiara .P. and Alina Surgical Gloves Balloons Band-aidsTennis shoesChewing gumSporting GoodsRubber trees must be about 5 years old before they produce latex.There can be as many as six hundred wild rubber trees in one thousand acres of rainforestBy: Chiara .P. and Alina
14Cacao TreesThe tree grows an oblong fruit commonly called a pod, which can be four to 12 inches long.The cacao tree is an evergreen that grows to about 45 to 75 meters.Pods are usually harvested at the end of the wet, or rainy, season.Each pod contains 20 to 60 reddish-brown cocoa beans up to an inch long.The fruits and flowers of the cacao tree grow directly from its trunk.
15Oil Palm The oil palm has thirty uses Some are: oil, Baskets, mats , Fences,drying racks,women items,palm wineEmilio and Bauti
16SapWhen we take some rock salt and perhaps some hot chilly peppers, one can drink sap.The sap is very sweet and contains little alcohol in the morning when it is first taken from the tree. The Sap is the sticky thing that you can find in the trees.This is the sap
17The first task at each tree is to collect the sap which has gathered inside the tree. To take the Sap from the trees you have to cut a hole on the top side of the fallen trunk .Then you must cut a thin slice off the side on the higher end of the hole so that the sap still inside the trunk will flow into the hole. With the sap you can make wine.
18Why are animals in extinction?? Because of hunting and habitat loss due to trees being cut down.Rainforests are loosing 137 animals every single day due to rainforest deforestation
19Juana Galperin and Sofi Goldemberg An animal must be both smart and strong to survive in this environment.Juana Galperin and Sofi Goldemberg
20Praying mantis’ excellent eyesight allows some to see movement up to 60 feet (18 meters) away. Mantis can turn their heads 180 degrees to. Typically green or brown and well camouflaged on the plants among which they live.Praying MantisMalcolm

22They are carnivores, feeding mostly on insects They are carnivores, feeding mostly on insects. ,They prefer crickets, flies, grasshoppers and moths.The Red-Eyed Tree FrogThe red-eyed tree frogs can even become a dark green or reddish-brown color.They are found in the lowlands and on slopes of Central America and as far as Mexico.Martín .N
23The Rain Forest is been cut down because poor people chop the wood to make money and for farming. It has been estimated that every minute an area of forest the size of 4 football pitches is cut down.Some Rain Forests may have existed largely undisturbed for 150 million years!
24Rainforest !Rainforests once covered 14% of the earth's land surface; now they cover a mere 6% and experts estimate that the last remaining rainforests could be consumed in less than 40 years.
25What does deforestation cause Animals will be destroyed, and many possible cures for life-threatening diseases.There were an estimated ten million Indians living in the Amazonian Rainforest five centuries ago. Today there are less than 200,000.
