RAINFOREST
By: Christina L. Jackson The business dictionary definition of rainforest is a dense forest of evergreen trees growing in regions of heavy year-round rainfall in tropical latitudes (such as Amazon Basin, Borneo, New Guinea, North-East India, and Zair Basin) and warm temperate latitudes (such as Eastern Australia, Florida, South Africa, South Brazil, South and Central China, South Japan, and New Zealand's North Island). Nearly half of these forests are in the Central and South America, mainly the lower Amazonia and along the coasts of Columbia and Ecuador. Tropical rain forests are the most complex and diverse ecosystems, and sustain the greatest concentration of biological diversity (half of all species of animals and plants) on the Earth.
The tropical rainforest ecosystem can be found in places near the equator in the countries of Asia, Australia, Africa, South America, Central America and on many of the Pacific Islands. The tropical rainforest ecosystem is also-called a tropical wet forest or a tropical moist broad-leaf forest. There several types of tropical rainforest
Lowland equatorial evergreen rain forests are forests which receive high rainfall (more than 2000 mm, or 80 inches, annually) throughout the year. These forests occur in a belt around the equator, with the largest areas in the Amazon Basin of South America, the Congo Basin of Central Africa, Indonesia, and New Guinea.
Moist deciduous and semi-evergreen seasonal forests, receive high overall rainfall with a warm summer wet season and a cooler winter dry season. Some trees in these forests drop some or all of their leaves during the winter dry season. These forests are found in parts of South America, in Central America and around the Caribbean, in coastal West Africa, parts of the Indian subcontinent, and across much of Indochina.
Montane rain forests, some of which are known as cloud forests, are found in
