7. Mineral cycling in three of the world's major forested
geo-ecosystems: (A) tropical rainforest; (B) deciduous summer forest;
and (C) boreal evergreen forest
A simple comparison of three of the world's major geo-ecosystems
(tropical rainforest, summer deciduous forest, and boreal
coniferous forest) in terms of a three-compartment systems model
of mineral cycling is shown in Figure 7. The three compartments
(circles) - the biomass (mostly vegetation), the litter (mostly
