Think what would happen, if seeds did not spread and remained at one place only.

उत्तर
If seeds would not spread and would remain in one place only, there can be many problems for those seeds. All the seeds would fall near the parent tree. This will prevent those seeds from getting enough sunlight, air, and water. As a result, most of the seeds would fail to germinate. New saplings, growing under a tree would not grow properly.
