The yield per acre of coffee berries varies enormously, because a single tree, depending on its size and on climate and altitude, is able to produce enough berries to make between one and twelve pounds of dried beans a year.
这个句子里depending不能改为dependent，因为depending和dependent的区别在于，前者伴随修饰谓语动词is able to produce，后者则是修饰名词single tree，会造成逻辑上不对 —— “一棵树依靠它的size”。
