The rapid nutrient cycling makes the ecosystem vulnerable if the vegetation cover is removed, as the underlying soil cannot support regrowth for long without the constant input from decomposing organic matter. Deforestation in these areas often leads to soil degradation.<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following statements about tropical rain forests are correct? 1.
