الشرح

Animals move seeds in two ways: they swallow a fleshy fruit and leave the seeds somewhere else later, or they brush past a fruit that catches on their coat and carry it until it drops. The claim about digestion gets the outcome wrong, since a seed that makes the journey has a coat tough enough to survive it, and a seed broken down inside an animal would disperse nothing.
