a plant responsabilirty is to spread its seeds ,and in many plants they want
to have their seeds attractive to eat to help in the spreading . many birds
and mammals are participating by eating them and defecating the ones not
digested some plants in fact require to have their seeds travel thru a gut
for sprouting ( coating get porous and allow the rehydratation of the seed.)
