What is the food chain in spring lake park

There is none

Plants... insects... amphibians and fish (possibly garden snakes)... small mammals including squirrels and rabbits, and birds including ducks, geese, gulls, turkey vultures, bald eagles, hawks, and an occasional blue heron (possibly barn owls). There may be a rare coyote since we hear them along the river and we live less than 15 miles from the park. No hunting is allowed in the park but there is fishing so I guess you would top the list off with humans if they ate the fish.
