Why have strawberries elaborated such a mechanism for seed dispersal? , Many birds and mammals feed on the tasty fruits, allowing the seeds to travel through the digestive system and eventually be excreted. Strawberries are just one fruit that scatters seeds through digestion and defecation, and the maturation process of the fruit includes ensuring that the seeds are ready to germinate. Dispersal Mechanisms: Seeds can be dispersed long distances by wind because they move in updrafts. Anemochory can be eliminated as strawberry seeds are imbedded in relatively heavy fruit, have no dispersal structures and their seeds are too large to be carried by wind.
