Tropical rain forest contain the greatest biodiversity in the world, and estimated to contain more than half of all species of living organism ( Wilson,1988). In this biome, there are over 15 million species of plant that live within it. This forest is so diverse that a lot of living organisms stay and do their life activity in this forest environment. Tropical rain forest are warm and wet forest with many tall trees that lies in about four layer which are the emergent, canopy, understory, and undergrowth layer. In most tropical rain forest, it rains almost every single day throughout the year. It grows in a narrow zone near the equator which occurs roughly within the latitudes 28 degrees north or south of the hemisphere. Besides that, it also one of the most exciting environments to explore. In addition, tropical rainforests store huge quantities of carbon, while producing much of the world's oxygen. Some people call tropical rainforests the lungs of the planet because they make so much of the oxygen that animals breathe. Another important role tropical rainforests play is in regulating global weather. They maintain regular rainfall. They also help prevent floods, droughts, and erosion .The largest rainforest in the world is Amazon rain forest in America. Rainforest also can be found in Asia, Australia, Africa, South and Central America, Mexico and on many of the Pacific, Caribbean, and Indian Ocean islands. For virtually all types of organisms, at almost any scale, diversity is higer in tropics than anywhere else in the earth. It is also known that more than a half of all species of living organism can be found in tropical rainforest. This diversity of diversities suggests that many different mechanisms influence the number of species in tropical rain forest. Studies show that a hectare in the Appalachians may have up to 30 species of trees; in the tropics a
