Webbed feet enable ducks to swim better by _________.

Webbed feet enable ducks to swim better by increasing the surface area on their feet. In swimming, being hydrodynamic, not aerodynamic, is important. Stuck particles between a duck’s toes would most likely not be a frequent problem. Webbed feet would not affect the duck’s density by much. The rate of heat loss maybe slightly higher because of the larger surface area, but heat loss is not essential for swimming.
