Explanation

When the rain forest is removed, a secondary forest often develops that includes soft-wood trees such as Musanga (Africa). Cecropia (America) and Macoranga (Malaysia). Efficient direct nutrient cycling by mutualistic micro-orgnisms is a remarkable property of rain forests that enable then to be as luxuriant on poor solis as on more fertile sites.
