our project will begin shortly..

Are all Tropical Forests, Rainforests?
Only a small percentage of the tropical forests are rainforests. To be a tropical rainforest, forested areas must:
Lie between the Tropic of Cancer and the Tropic of Capricorn.
Receive rainfall regularly throughout the year (80-400 inches per year).
Remain warm and frost free all year long (mean temperatures are between 70 and 85F) with very little daily fluctuation.

Consequently, many forested areas in the tropics are not rainforests. Forests that receive irregular rainfall (monsoons followed by a dry season) are moist deciduous forests. Trees in these forests may drop their leaves in the dry season.



Strata of the Rainforest
Different animals and plants live in different parts of the rainforest. Scientists divide the rainforest into strata (zones) based on the living environment. Starting at the top, the strata are:

EMERGENTS: Giant trees that are much higher than the average canopy height. It houses many birds and insects.

CANOPY: The upper parts of the trees. This leafy environment is full of life in a tropical rainforest and includes: insects, birds, reptiles, mammals, and more.

UNDERSTORY: A dark, cool environment under the leaves but over the ground.

FOREST FLOOR: Teeming with animal life, especially insects. The largest animals in the rainforest generally live here.

Soil in Rainforest
The soil of a tropical rainforest is only about 3-4 inches (7.8-10 cm) thick and is ancient. Thick clay lies underneath the soil. Once damaged, the soil of a tropical rainforest takes many years to recover. Animals that Live in Rainforests:
Ridiculously huge numbers of animals live in rainforests, including microscopic animals, invertebrates like insects and worms, fish, reptiles, amphibians, birds, and mammals. The different rainforests of the world support different populations of animals.

South America

insects morpho butterfly, Julia butterfly, Monarch butterfly, and millions of other insects
mammals jaguar, ocelot, didelphid opossums, sloth, howler monkey, spider monkey, capybara, many bats, marmosets, procyonids, peccaries
birds quetzal, macaw, tinamous, curassows, hoatzins, hummingbirds, eagles, ovenbirds, antbirds, flycatchers, puffbirds, toucans, jacamars, tanagers, tapirs, troupials, honeycreepers, cardinal grosbeaks, xenops
reptiles anaconda, caiman, iguanas, lizards, microteiid lizards, boas, and coral snakes
amphibians poison arrow frog, etc.
fish electric eel, piranha, and millions of other animals.

THIS IS THE BORING PART SO DRINK YOUR COFFEE FIRST..

FACTS
Tropical rainforests cover about 6% of the Earth's total land surface. They are mainly located around the belt at the equator. The climate of the rainforest is warm most of the year and has a lot of rain through most of the year. The climate is perfect for animals and plant growth. Even though the rainforests cover such a little amount of land mass of the Earth, they are home to the largest number of plant and animal species in such a concentrated area. Scientists believe that the tropical rainforests of the world might hold up to ninety percent of the plant and animal species on earth.

The Amazon drains the world's largest tropical rainforest, and is thought to have about 3000 species of fish, more than are contained in the entire North Atlantic. It is estimated that a typical patch of rainforest just six kilometers square contains as many as 1500 species of flowering plants, 750 species of tree, 400 species of bird, 150 species of butterfly, 100 species of reptile, and 60 species of amphibian. There are so many insects that they can only be guessed at, but one-hectacre (2.5 acres) may contain as many as 42,000 species.

Climate and Location
Tropical rainforests are mainly located around the belt at the equator, in the Amazon basin in South America, the Congo basin and other lowland regions in Africa, and they are both on the mainland and the islands off of Southeast Asia. They are especially abundant on Sumatra and New Guinea. Small areas are also found in Central America and along the Queensland coast of Australia.

The tropical rainforests climate is very warm, it has an average annual temperature of greater than 20 degrees celsius. They also have very little seasonal variation in temperature or day length, which is very favorable for plant growth. The tropical rainforest's temperature ranges from 20 to 25 degrees celsius and they have more than 250 centimeters of annual rainfall. The main climate control of the tropical rainforests are latitude.

Animals
The animal of the tropical rainforest are a wide variety that adapt to their surroundings in many ways. One of the most common and effective camouflage is looking like a leaf dead or alive. The rainforest floor is scattered with dead leaves so the animals blend in very well and would be very hard to see from above like a bird would. Moths, treefrogs, and katydids also use this method. Animals also use coloring to warn predators that they are poisonous. Some of the brightly colored animals are just bluffing, but one that definately isn't is the poison arrow frog. The poison arrow frog comes in many different colors, the retiulated; dendrobates auratus is an aqua and black colored poison arrow frog. The D. leucomelas is a bright yellow and black colored poison arrow frog. The D. granuliferus' top half is red, its underside and back legs are green. The poison arrow frogs get their name because some rainforest tribes use the secretions from their skin to poison the tips of their blow gun darts.

Vegetation
Young leaves if several jungle trees are red, and in the canopy or from the air such trees often appear to be in flower. Vegetation often interact with animals, birds and insects. The ceiba tree is covered in vivid red flowers that attracts numerous insects and humming birds, which drink the necter, collect the pollen, and fertilize the tree. The rainforest also have flowers that people have domesticated. The orchids come in many different colors, some are big and yellow and others are small and pink. Orchids are mainly found in Aisa and some parts in South America. Most of the rainforest leaves have pointed ends so that the rain can drip off. If this didn't happen the leaves might mold.

Destruction of the Rain Forest
Rainforests are dissappearing at about 80 acres per minute, day and night. The rainforest is home to over half of all of the species known in the world. There are many undiscovered species that are being destroyed. Many of these species are possible cures for cancer and AIDS etc. Much of the destruction is done by Forest Alliance of British Columbia. Also as the population of earth grows, the need for forest products is increased and causes them to destroy even more rainforests to meet the demands. If this destruction continues, major climatic changes will occur. This will happen because when the forests are destroyed carbon dioxide is released which, in turn, causes the greenhouse effect. Ranching and logging for materials for houses, furniture, and paper products are also major destroyers of the rainforest. The tropical rainforest once covered more than 16% of the earth's total land surface, but now covers less than 6% of the earth's total land surface. Boycotts are the most effective ways of stopping destruction of the rainforest. Boycotting fast food resturaunts who use hamburger from cows who grazed on rainforest land, for example. Tourism also adds to the prevention. People seeing how the forest looks and all of the living going on in it causes them to want to make changes so that the rainforest can continue to grow. .

Health Issues
The rainforest provides many different purposes. But, one of its most important resources is the fact that most of the world's oxygen production comes from the rainforest. With the rainforest decreasing everyday' the oxygen supply will be less and less in the future, due to the increasing need for more land to build more businesses.

The cures for major diseases, such as malaria, are contained in plants that are found in the rainforest.

this is what people do..they get animals from our enviroment and make money out of it..which is wrong. let them live int heir own habitats and give thema a peaceful place to live in...


but others..they just enjoy their company with their pets..>
MAY THE FORCE BE WITH YOU..
it doen'st matter how big they are..you just have to learn how to care for them..


event hough this pic is not from a tropical rainforest..you kinda get the point right?? this is something for the aquatic biome...i found nemo..and ready to be eaten..
