a. Some projections like hooks, barbs, spines, bristles and stiff hair are present on the surface of seeds which get attached to the skin of animals and carried to distant places and hence dispersed.
b. Seeds are embedded in fleshy and edible fruits in some plants that attract animals to eat them.
c. The seed itself can also become an attractive food for animals like squirrels and acorns.
