Minerals in the plants are not lost when the leaf falls .

Explanation

Minerals are remobilised from older dying leaves to younger leaves. This phenomenon can be seen in deciduous plants. Elements like phosphorus, sulphur, nitrogen and potassium are easily mobilised, while elements like calcium are not remobilised. Small amounts of material exchange takes place between xylem and phloem. Hence minerals in the plants are not lost when the leaf falls.
