Explanation:

Scarification of seeds is done to break the dormant seed’s outer seed coat open to facilitate germination. In some plants, the seeds have hard outer coat and make it impermissible to water and gases and thus delays germination. Animals do help to scarify seeds by eating the hard-outer covering. Seeds of plants like morning glory, purple hyacinth beans are examples where scarification is done.
