Even in the tropics many plants and trees still lose leaves and some plants and trees actually die; and these then break down in the soil continuing to provide the nutrients that the plant or tree kingdom requires to continue to grow and subsist.

• 甚至在热带许多植物和树仍然会落叶，并且有些植物和树实际上会死去;之后这些死去的植物树木在土壤中分解从而为植物或树木王国提供维生与成长的营养素。
