For this reason, even though the vegetation may be lush, the soil itself contains few available nutrients.
When trees and plants die, their nutrients are recycled to maintain the forest. A Nutrients in rainforests are recycled at various rates, due to differences in rates of decomposition and variations in soil chemistry. In tropical rainforests, the warm temperatures and abundant precipitation cause most organic material to decompose in a few months to a few years. B Because decomposition is so rapid, relatively little organic material accumulates on the floor of tropical forests. As the vegetation dies and decays, the roots of the trees quickly absorb the nutrients. C Most of the nutrients supporting the rainforest—about 75 percent of those in the ecosystem—are stored in the woody trunks of trees, while only about 10 percent are contained in the soil. The relatively low concentrations of nutrients in the soil are a result of the fast cycling time rather than a shortage of these elements in the ecosystem. D
