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. The soil is, therefore, always shaded, and very little vegetation is able to survive at ground level. 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
Fact sheet: Tropical Rainforest Animals Where can you find an antelope the size of a rabbit, a snake that can fly, or a spider that eats birds? All in tropical rainforests, of course! Tropical rainforests are home to the largest and the smallest, the loudest and the quietest of all land animals, as well as some of the most dangerous, most beautiful, most endearing and strangest looking animals on earth. You've probably heard of some of them: jaguars, toucans, parrots, gorillas, and tarantulas all make their home in tropical rainforests. But have you ever heard of the aye-aye? Q: Why do more animal species live in the rainforest than other parts of the world? A: Scientists believe that there is a great diversity of animals because rainforests are the oldest ecosystems on earth. The nearly perfect conditions for life also helped contribute to the great number of species. Some rainforest species have populations that number in the millions. Q: Which type of rainforest species is most numerous? Extinction is a natural process.
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. Within the World Wildlife Fund's biome classification, tropical rainforests are thought to be a type of tropical wet forest (or tropical moist broadleaf forest) and may also be referred to as lowland equatorial evergreen rainforest. 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. Forest structure Ecology
Climate Tropical rainforest climate Worldwide zones of Tropical rainforest climate (Af). A tropical rainforest climate, also known as an equatorial climate, is a tropical climate usually (but not always) found along the equator. Regions with this climate typically feature tropical rainforests, and it is designated by the Köppen climate classification. Description Distribution Upland rainforest in Borneo. A tropical rainforest climate is usually found at latitudes within five degrees North and south of the equator, which are dominated by the Intertropical Convergence Zone. Some of the places that have this climate are indeed uniformly and monotonously wet throughout the year (e.g., the northwest Pacific coast of South and Central America, from Ecuador to Costa Rica, see for instance, Andagoya, Colombia), but in many cases the period of higher sun and longer days is distinctly driest (as at Palembang, Indonesia) or the time of lower sun and shorter days may have more rain (as at Sitiawan, Malaysia).

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. They are also found on every continent, except Antarctica. 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. What would you do if you couldn’t have that cup of coffee in the morning? Want some more amazing rainforest galleries?

You can see on the picture in the upper left corner that the Amazon is the dark green area on the map. This zone which covers much of the northern half of that is east of the and north of the which centers at the equator. In an average year in a tropical rainforest, the climate is very humid do to all of the rain which amounts to about 250cm per year. The climate is found near the equator. 40o F.

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';. The humidity of the rainforest encourages such adaptations which would be impossible in most temperate forests with their much drier conditions.
Plants Top 10 facts about the Amazon Rainforest | The Inside Track | Travel Blog from On The Go Tours The Amazon is synonymous with Central and South America – it’s the largest of the rainforests, supporting a huge number of plants and animals and hugely important to our own survival. Taking up most of the Amazon Basin, the Amazon rainforest is mostly contained within Brazil, and stretches into Peru, Ecuador, Bolivia, and smaller parts in some other South American countries. Here are ten interesting facts about the Amazon (and rainforests in general) that you may not have heard before. 1. Around 80% of the food we eat originally came from rainforests. Some of the more popular examples include coffee, chocolate, rice, tomatoes, potatoes, bananas, black pepper, pineapples and corn. 2. 3. 4. 5. 6. Over half the world’s plants and animals can be found in the rainforests. 7. 8. 9. 10. Sunset on the Amazon River Clearly now is the time to visit this amazing region learn more about this natural marvel and to help gain and spread awareness about how urgent the need to save the rainforest is.
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. 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. Emergent trees are spaced wide apart, and are 100 to 240 feet tall with umbrella-shaped canopies that grow above the forest. Plant Life Besides these four layers, a shrub/sapling layer receives about 3 % of the light that filters in through the canopies. Animal Life
