Question

Why do leaves drop ofg seasonally?

Answer 1

Leaves must fall. Evergreens can hang on to their leaves through winter, because their foliage is coated in a wax that helps protect against cold, and their cells bear anti-freeze chemicals that ward off winter's worst woes. Not so for broadleaf, or deciduous, trees.

It is the way plants remove waste products from from their body. They send waste products and o some leaves. And when the leaves are filled with wastes they droop and fall down.
