What adaptations should one expect of the seed coats of angiosperm species whose seeds are dispersed by frugivorous (fruit-eating) animals, as opposed to angiosperm species whose seeds are dispersed by other means?

Question

Quizplus · Accepted Answer

Angiosperm species whose seeds are dispersed by frugivorous animals need seed coats that can withstand high acidity and resist the animal's digestive enzymes, as the seeds can be ingested and excreted intact. This adaptation increases the chances that the seeds will remain viable after passing through the animal's digestive system and be dispersed over a wider area.
