Missing arrow in concept map for balls pushing out water?

In the final concept map for balls pushing out water, is there supposed to be an arrow from weight to water? This would indicate that both size (volume) and weight impact displacement of water. For example, a beach ball may displace less water than a bowling ball or even a baseball.
