Question

why do leaves fall for 3rd class​

Answer 1

Answer:

Leaves fall off trees when they aren't doing their job any more. A leaf's job is to turn sunlight into food for the tree. To do this, the leaf needs water. ... The tree doesn't want to waste all the good things in the leaf, so it takes the nutrients from the leaf back into the stems and roots.

Answer 2

Answer:

The main reason for leaf drop on most trees is that, come winter, it gets pretty cold and dry in our part of the world. Rather than expend energy to protect these fragile organs, trees shed leaves to conserve resources.
