The tropical rainforest biome is home to some of the world's most densely populated forests. In fact, over half of the world's plant and animal species live in these forests. All of these plant and animal species fit into a biome that covers only seven percent of the world's land.
The tropical rainforest also receives more rain than any other biome. The tropical rainforest in Cherrapunji, India once received 1,042 inches (2,647 centimeters) of rain in one year.
Tropical rainforests usually reside in or near the equator and are located in more than forty countries. There are three major rainforest areas. There is a large rainforest in Central Africa that covers more than 460 million acres (186 million hectares). The second largest rainforest, engulfing more than 600 million acres (243 million hectares), is in Southeast Asia and on such islands as the Philippines and New Guinea. The largest rainforest in the world can be found in Central and South America. It covers almost 1,370 million acres (555 million hectares) of land.
There are two different types of rainforests: lowland forests and cloud forests. Lowland forests are found in areas of low elevation. They contain tall trees with high canopies. They receive intermittent precipitation throughout the year. Cloud forests are found in mountainous regions and growth is usually thicker than lowland forests. Cloud forests gain moisture through mist, rain, and clouds.
