I believe that Largemouth bass prey more heavily on fry than Smallmouth bass would. It seems that Smallmouth tend to prefer things other than fish when they are smaller, tending to eat insect larvae if they are available only becoming piscivorous later in life when they pumpkinseeds have already had a chance to mature and spawn. That is one theory anyway.
Once you get into the sunfish area of the food chain things do get a little hectic for a smallmouth pond.
