Transcript of Tropical Rainforest
of rain a year Lowland equatorial evergreen rainforests -The temperature rarely gets
above 93 degrees Fahrenheit Moist deciduous and semi-evergreen seasonal forests Montane forests Flooded forests -Rarely goes below 68 degrees
Fahrenheit -Average humidity between 77-88% The rainforest has 4 distinct layers, they are: The forest floor The understory And the emergent layer -Equatorial climate Products such as coffee, yam, bananas, mangoes, and sugarcane originally came from the rainforest. Plants of the Tropical Rainforest -Hot and Wet -Average temperature is about 77
degrees Fahrenheit -Bengal Bamboo -often grows as scattered patches of undergrowth The biggest danger to rainforests is deforestation -can grow anywhere from 40-80 ft. high -native to India, Burma, Bangladesh, Myanmar, and Thailand Several endangered species live in the rainforest, including: -Bougainvillea Harpy Eagle -grows in the Amazon rainforest in South America African forest elephant Chimpanzee Bengal tiger -it can grow as tall as 30 ft. -it can grow as vines, trees, or shrubs with sharp thorns The
canopy -No dry season -Curare -grows as a large vine in the canopy of the South American Rainforest -the vine of this plant can be 4 in. thick at the base -the active ingredient in Curare, D-tubocurarine, is used in medicine for madness, bruises, fever, and kidney stones -Durian -it is considered to be one of South Asia's most ancient and primitive trees -grows in lowland rainforests, and is native to Borneo, Malaysia, and Indonesia -lifespan of 80-150 years, but it can live longer. It is believed that Durians only die when they're blown down by a storm or cut down by humans -it is dependent on a small, nocturnal bat, the dawn bat, for its pollination. This is a mutual relationship because both organisms benefit: the Durian is pollinated and the bat gets a meal -the fruit of the durian, referred to as the "king of fruit" in southeast Asia, is widely consumed and can cost up to 7$ in America -Strangler Figs -it is one of the most important plant species of a rainforest ecosystem -there are over 1000 different species of Ficus (the genus of strangler figs) and they can be found in every major rainforest, tropical continent, and islands around the world -strangler figs are fed on by parrots, pigeons, toucans, and gibbons -since strangler figs are fed on by just about every organism in a rainforest biome, they are considered a keystone species -in some rainforests, up to 70% or its animals depend on figs from this plant Animals of the Tropical Rainforest -Bengal tiger -can weigh up to 575 lbs. and can be up to 10 feet long and 3 feet tall -lifespan of about 15 years -this tiger, like all other tigers, is a carnivore, and eats boars, wild monkeys, and other animals -in 1900, there were 50,000 bengal tigers in the world, but now there are just around 4000. In response to this drastic in the tiger population, Prime Minister Indira Ghandi started "Project Tiger." This act made it illegal to hunt tigers or trade any of their parts -Harpy Eagle -one of the world's largest and most powerful eagle species -lives in the tropical lowland rainforest of central and South America, Southern Mexico, Eastern Bolivia, Southern Brazil, and the northernmost parts of Argentina -they are carnivores, and hunt monkeys, sloths, iguanas, large rodents, as well as other birds -they are also an endangered species -African Forest Elephant -Chimpanzee -Linne's Sloth -Third species of elephant
-subspecies of the African Elephant
-58% difference between it and the African Elephant
-smaller and stockier than Savanna elephants
-only get to be about 8 feet tall
-endagered species -3 to 5 feet tall
-weighs from 99 to 176 pounds
-favorite food fruits and young leaves
-communities are made up of 15 to 100 members
-endangered species -white/tan face fur is black/dark brown
-28 to 29 inches long
-weighs about 9 to 19 pounds when fully grown
-life span of 27 to 32 years
-eats leaves, bark, buds, fruit, and sometimes small animals such as: mice, squirrel, and kangaroo rats THE END! -A tropical rainforest is a type of ecosystem that is densely populated with tall trees, as well as a rich bio-diversity of plants and animals, that averages 50-260 inches of rain each year. -In order to survive the hot, wet, conditions of the tropics, plants have developed special features, called adaptations. Trees, instead of having thick bark, have thin and smooth bark. The leaves of rainforest trees deal with the large amounts of rain with their big, thick and waxy leaves. They also have "drip tips" that let the rain drain off quickly. -Just like plants, animals have also developed adaptations to survive the harsh conditions of the rainforest. Some animals have adapted to eating a specific plant or other animal that few others eat. This ensures that they will always have a plentiful food source, limiting competition and helping them survive. They have also developed specific adaptations on their body to make themselves better able to do certain things. Parrots and toucans eat nuts, and have developed big strong beaks to crack open the tough shells of Brazil nuts.
