  2. CLIMATE: The tropical rainforest's climate is very warm, it has an average annual temperature of greater than 20° 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° Celsius and they have more than 250 centimeters of annual rainfall. The main climate control of the tropical rain forests are latitude.

  3. COLATION IN THE WORLD: Tropical rain forests cover about 6% of the Earth's total land surface area. They 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.

  4. DOMINANT ANIMALS: Fontwork Fontwork Fontwork Fontwork POISON FROG MACAWS Macaws are the largest of all parrots. There are 16 different species of macaws and they range in size from a little over three feet to one foot. They have beautiful, graceful, tails that are as long or longer than their bodies. They also have long, pointed wings that enable them to fly swiftly. Poison-arrow frogs are social frogs found in Central and South America. They are known by their bright colors which warn other animals that they are poisonous. Its poison is one of the most powerful known and can cause paralysis or death. It is so potent that one millionth of an ounce can kill a dog and an amount smaller than a grain of salt can kill a human. One frog carries enough poison to kill about 100 people. Native hunters use it on the tips of their arrows which is how the frog got its name. SLOTHS Sloths are extremely slow-moving mammals found in the rain forest canopies of Central and South America. There are two species of sloths:two-toed and three-toed. Most sloths are about the size of a small dog and they have short, flat flat heads. Their hair is grayish brown but, at times they look grey-green in color because they move so slowly that tiny camouflaging algae grow all over their coats.

  5. DOMINANT PLANTS: KAPOT TREE Bengal Bamboo JAMBU Jambu is a small tree or large shrub which grows on the average. of 10 to 20 feet in height. Branches grow close to the ground from a short, crooked trunk. The crown is open and non-symmetrical. It likes plenty of rain evenly spaced throughout the year. The Kapok tree is an emergent tree of the tropical rainforests, and is often described as majestic. It can grow to a height of 150 feet or more, towering over other trees in the rainforest. Originally a native to South America it now has spread to the primary rainforests of West Africa, and the Southeast Asian rainforests of the Malay Peninsula, and the Indonesian archipelago. The Bambusa tulda can be found in the biome of the Southeast Asian rainforest. It often grows as an undergrowth scattered or in patches in the forest. It does very well in a moist environment with a lot of rainfall. It likes temperatures between 40 degrees Fahrenheit and 100 degrees Fahrenheit. Rainforests get around 100 inches of rain per year

  6. 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 rain forest 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 Asia and some parts in South America. Most of the rain forest leaves have pointed ends so that the rain can drip off. If this didn't happen the leaves might mold.

  7. NEGATIVE FOR HUMAN: • As tourism becomes more popular in the tropical rain forests there are many different negative impacts that come from it, these being depletion of natural resouces, pollution, and more. Taking walks/hikes in the forest, off-roading or biking and camping all can trample vegetation, introduce weeds and change plant composition. Bringing in any outside influences that come in contact to the plants and nature of the forest can destroy or leave a major impression on the plants. There are also many other environmental impacts on the forest caused by tourism such as: changes in soil condition, increased soil erosion, alterations of faunal composition, increase and introduction of weeds, development of social trails or paths through the forest, changes in water quanlity, habituation of native fauna, alterations of plant life and composition, and spread of soil pathogens.

  8. POSITIVE FOR HUMAN: • Onset dates and prevailing wind currents of the southwest summer monsoon. • Despite the negative effects of tourism in the tropical rain forests, there are also several important positive effects. • »An increase in tourism has increased economic support, allowing more revenue to go into the protection of the habitat. Tourism can contribute directly to the conservation of sensitive areas and habitat. Revenue from park-entrance fees and similar sources can be utilised specifically to pay for the protection and management of environmentally sensitive areas. Revenue from taxation and tourism provides an additional incentive for governments to contribute revenue to the protection of the forest. • »Tourism also has the potential to increase public appreciation of the environment and to spread awareness of environmental problems when it brings people into closer contact with the environment. Such increased awareness can induce more environmentally conscious behavior. Tourism has had a positive effect on wildlife preservation and protection efforts, notably in Africa but also in South America, Asia, Australia, and the South Pacific.
