You can get marginal #'s (less than a whole one) of acorns for filling in missing data info. You know how you will find a plant & it has some of the fields filled in but some of the fields are missing info.? Fill those in or as many as you can find research to support & depending on how many were filled in before you started & how many you filled in, then the system awards you portions of acorns. Did I make sense?
