Answer 1

1.Although sheer numbers of seeds do in fact ensure offspring, you must also remember trees (and most all plants really) are relatively immobile. Not only do they want to product offspring, but they want to ensure some of those offspring travel a little ways. Often, the seeds that germinate under the parent tree are choked out, but the seeds that travel away from the parent tree germintate and grow to adulthood. Whether they travel by way of wind, bird, or clinging on to animals walking by, is up to the species.
Sheer numbers ensure SOME of them will travel a little ways

2.Seeds are the product of the ripened ovule, after fertilisation by pollen and some growth within the mother plant. The embryo is developed from the zygote and the seed coat from the integuments of the ovule.

3. The above specified seed like coconut are transported not by wind or weather but by human or animal displacements
