Discussion Based on the data at Tables 4c.2 and 4c.3‚ it is evident that the tropical rainforest has higher species richness than the tropical grassland ecosystem. However‚ when based in the indices on Diversity‚ Similarity and Dominance in the tropical grassland and tropical rainforest data‚ the Simpson Indices favor the data for the tropical rainforest as more diverse than the tropical grassland. The Simpson Indices‚ as defined in Cuevas et. al (2012)‚ is based on dominance and as the number of

Tropical rainforests are currently a habitat that is currently experiencing serious losses. Some major reasons why the rainforest are having serious losses are because of agricultural expansion‚ urbanization‚ and the extraction of wood. Currently‚ the biggest cause is agricultural expansion which turned the forest into pastures and cropland to meet the growing needs for food. A study shows that more than 80 percent of the new farmland created in the tropics between 1980 and 2000 came from forests

The Tropical Rainforests There are many different ecosystems on this planet. They include tundra’s‚ desserts‚ grasslands‚ etc. However‚ the tropical rainforest is truly the world’s most diverse biome in both structure and species diversity. The Tropical rainforest is characterized by a dense growth of trees and by the continuously canopy that is formed by the broad- leaved Evergreen trees. There is also large amounts of precipitation annually and there is no dry season‚ which is a major factor

Rain Forests Rainforests cover only 6% of the earth’s surface but they house more than half of the world’s animal and plant population. Rainforests have beautiful layered ecosystems and water features that home massive amounts of living things. There is a very diverse food chain in rainforests. Deforestation is limiting what the rainforest can provide to the world. Rainforests are very large forests that help the earth in many ways. They house many plants‚ animals‚ insects‚ and even

TROPICAL RAINFORESTS - WHERE AND WHAT ARE THEY? _______________________________________________ Tropical rainforests are found across the world between the Tropic of Capricorn and the Tropic of Cancer‚ 22.5° North and 22.5° South of the Equator. Almost half of the remaining tropical rainforest is found in tropical America‚ a bit more than a third in Asia and Oceania‚ and fifteen percent in Africa. Tropical rainforests cover approximately 8% of the world’s land surface - an area of approximately

The rain forest has large amounts of rain because it is very hot and wet. Tropical rainforests are defined by rainfall. They would not survive without it. Not all rain forests have tropical sunny

1. Where Are The Worlds Rainforests Located? Tropical rainforests are located around the equator. The weather is bright and sunny for about the same time every year‚ the reason for this being is because they’re located between the tropics of Capricorn and Cancer‚ were sun consistently shines. On a yearly basis approximately 160-400 inches (4‚064mm-10‚160mm) of rainfall is recorded on average for each rainforest‚ surprisingly these sunny and wet conditions are quite stable.

should tropical rain forests be conserved? Tropical rainforests are thought to posses more plants and animals than any other forests on earth. Most tropical rainforests are located around and near the equator‚ they have existed on earth for hundreds of millions of years. But they are among the most endangered ecosystems globally due to humans. They are an important part of human life and are know as the “lungs of the planet” they have many animals‚ and many natural medicines come from tropical rainforests
