Question

A ripe apple falls to the ground. How can this help an apple tree reproduce

Answer 1

When the apple falls to the ground it is prey to animals and insects that eat the fleshy fruit. At the core of the apple are the stored seeds. Once the fleshy fruit is eaten the seeds are able to be dispersed by wind or animals. Once the seed is in the right environmental conditions it will begin to grow and reproduce as previously explained.  

Answer 2

Well, when an apple falls and stays there for some time, the apple rots or decomposes after the actual apple is gone the seeds are left there on the ground, and after nature does its thing, it'll start to grow into a tree. Thus helping the tree reproduce
