Answer 1

Originally, it was the plant bribing an animal.

Most plants with nutritious fruits also have seeds that can survive a trip through the an animal’s digestive system. For these plants, the way they spread their seeds is by having the fruit get eaten by the right kind of animal; and then the seeds grow in the animal’s poop. Over time, the plants that gave more nutrients got eaten more, so spread their seeds more.

The modern human reason is selective breeding. Humans specifically planted seeds from plants that gave better fruits; and provided protection, planting, and nutrients – which resulted in more and more nutritious fruits over time.
