Dissuscs how forest acts an self sustaing ecosystem
The term primary rainforest refers to untouched, pristine forest that exists in its original condition i.e .its? development has not been perceptibly influenced by man. Everything else is secondary rainforest, which has been disturbed in some way, naturally or unnaturally.
48 percent of all forests are located in the tropics or subtropics. The tropical forests are located between the tropics of Cancer and Capricorn, about 23.5 degrees latitude north and south , respectively. With around 18.5 million square kilometres, they cover around 40 percent of the tropical land area.
Self-contained Ecosystems
Three quarters of the soil in the tropics is very low in nutrients. It is very old and therefore much of its mineral content is already washed out. The fact that rainforests can exist despite infertile soil is due to a perfectly balanced, inbuilt recycling system.
