Rainforest Biomes The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches (125 to 660 cm.) of rain falls yearly. Rain forests belong to the tropical wet climate group. The temperature in a rain forest rarely gets higher than 93 °F (34 °C) or drops below 68 °F (20 °C); average humidity is between 77 and 88%; rainfall is often more than 100 inches a year. There is usually a brief season of less rain. Rainforests now cover less than 6% of Earth's land surface. A tropical rain forest has more kinds of trees than any other area in the world. About 1/4 of all the medicines we use come from rainforest plants. All tropical rain forests resemble one another in some ways. Despite these differences, each of the three largest rainforests--the American, the African, and the Asian--has a different group of animal and plant species. Layers of the Rainforest There are four very distinct layers of trees in a tropical rain forest. Plant Life Animal Life

Plants The Plants of the Rainforest A tropical greenhouse More than two thirds of the world's plant species are found in the tropical rainforests: plants that provide shelter and food for rainforest animals as well as taking part in the gas exchanges which provide much of the world's oxygen supply. Rainforest plants live in a warm humid environment that allows an enormous variation rare in more temperate climates: some like the orchids have beautiful flowers adapted to attract the profusion of forest insects. Competition at ground level for light and food has lead to evolution of plants which live on the branches of other plants, or even strangle large trees to fight for survival. The aerial plants often gather nourishment from the air itself using so-called 'air roots';.

Plants climate. A tropical rainforest is an ecosystem type that occurs roughly within the latitudes 28 degrees north or south of the equator (in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn). This ecosystem experiences high average temperatures and a significant amount of rainfall. Rainforests can be found in Asia, Australia, Africa, South America, Central America, Mexico and on many of the Pacific, Caribbean, and Indian Ocean islands. Overview Tropical rainforests can be characterized in two words: warm and wet. Tropical rainforests are among the most threatened ecosystems globally due to large-scale fragmentation due to human activity. History Tropical rainforests have existed on Earth for hundreds of millions of years. Types of tropical rainforest Several types of forest comprise the general tropical rainforest biome: Lowland equatorial evergreen rain forests are forests which receive high rainfall (more than 2000 mm, or 80 inches, annually) throughout the year.

Rainforests Facts Facts about Rainforests Do you know how many tropical rainforest plants have been identified as having anti-cancer properties? Or how many continents around the world contain rainforests? And just how quickly are the world's rainforests disappearing? Find out the answers to these questions and more as you check out these interesting rainforest facts! Facts about the Global Coverage of Rainforests Covering less than 2 percent of the Earth's total surface area, the world's rainforests are home to 50 percent of the Earth's plants and animals. Facts about the Rainforest as Part of our Global Environment and Well-being Rainforests act as the world's thermostat by regulating temperatures and weather patterns. Facts about the Abundant Life and Important Resources that Rainforests Share with Us A typical four-square-mile patch of rainforest contains as many as 1,500 flowering plants, 750 species of trees, 400 species of birds and 150 species of butterflies.

Animal Earth Floor: Biomes Tropical Rainforest: Plants Although tropical rainforests receive 12 hours of sunlight daily, less than 2% of that sunlight ever reaches the ground. The tropical rainforest has dense vegetation, often forming three different layers--the canopy, the understory, and the ground layer. Frequently, people think of the tropical rainforest as a "jungle" where plant growth is dense even at ground level. However, the canopy created by the tall trees (100-120 feet) and the understory, prevents sunlight from reaching the ground. Vegetation can become dense at ground level near riverbanks and on hillsides. Plant adaptation Plant survival in a tropical rainforest depends on the plant's ability to tolerate constant shade or to adapt strategies to reach sunlight. Competition for sunlight by plants is sometimes deadly. Back | Next

Earth Floor: Biomes Tropical Rainforest The tropical rainforest is a hot, moist biome found near Earth's equator. The world's largest tropical rainforests are in South America, Africa, and Southeast Asia. Tropical rainforests receive from 60 to 160 inches of precipitation that is fairly evenly distributed throughout the year. The hot and humid conditions make tropical rainforests an ideal environment for bacteria and other microorganisms. Back | Next

Tropical Rain Forest As you can see from the map to the right, the tropical rainforests are, indeed, located in the tropics, a band around the equator from 23.5 N (the Tropic of Cancer) to 23.5 S (the Tropic of Capricorn) (red lines on map, right). Because the Earth tilts 23.5 degrees on its axis as it travels around the sun, at some point in the year (the solstices, June 22nd in the north, December 22nd in the south) the sun will be directly overhead on one of these lines. At the equinoxes the sun is directly over the equator. Within this band, solar radiation is most intense, and thus the surface of the planet warms the most. Not all of the land in the tropics is tropical rainforest. {*style:<a href=''>*}{*style:</a>*}Another biome similar to the tropical rain forest is the{*style:<b>*} cloud forest.

fires-could-turn-amazon-rainforest-into-a-desert-as-human-activity-and-climate-change-threaten-lungs-of-the-world-says-study-9259741 One of the last great wildernesses on earth – known as the lungs of the world – is balancing dangerously close to a “tipping point” where forest fires will become so commonplace and extensive that they will change much of the landscape forever, scientists said. Although fires have always occurred in Amazonia, they have been largely controlled by the natural humidity of the region. Now, however, the drying out of the rainforest threatens to ignite the tree-filled habitat – with its rich biodiversity – and convert it almost overnight into barren desert, they warned. For the first time, scientists have shown in experiments on the ground how extreme, dry weather combined with the effects of human activities can create a tinderbox environment where intensely damaging forest fires can spread easily, killing trees that have taken hundreds of years to grow. The researchers monitored the three 50-hectare plots of Amazon rainforest over an eight-year period.

Facts Ten Amazing Rainforest Plants Our surroundings are sometimes taken for granted. Even something as unique as the rainforest is forgotten. It seems a little bit of knowledge and a shove in the right direction can get people to appreciate the environment. So, why not start with the wonder that is the rainforest? Even though rainforests only cover less than two percent of the Earth’s entire surface area, they are home to 50 percent of the plants and animals. You’re probably thinking “I know all there is to know about bananas; I eat them for breakfast and can make delicious banana bread.” Habitation: Found in Central America, South America, Africa, Southeast Asia and non-tropical regions like the United States thanks to modern agricultural technologies. Known for their beauty, orchids are the largest family of plants in the world. Habitation: Extremely adaptable and grows in most climates with the majority being found in Central America, South America and in countries along the Andes Mountains.
