Importance of Pollination
Higher yields in agriculture.
Fruits & Seeds require pollination first.
Diverse genetic combinations.
Why use animals as

Answer:
There is a high degree of pollinator
specificity.
Plants attract animals using a variety of
adaptations including:
> Color
> Scent
> Heat
> Rewards (pollen & nectar)  The goods!
