Different ecosystems have different soil qualities. For example, temperate
forests have a lot of organic carbon available for plants. In the tropics,
although there is a great amount of fecundity, most of the organic carbon is
tied up in living plants and fungi. That's why the tropical rainforest, when
cleared, is burned to provide a quick (and short-lived) nutrient source.
