This graphic is misleading. Weight alone isn't going to feed a population. kcal/L is more meaningful. The ranking at a glance still generally holds true, but comparing tofu to chicken we see chicken uses less water per kcal.

830kcal/1kg tofu = 83kcal/100g * 10
2390kcal/1kg whole chicken = 1429kcal/598g * 1.67

Chicken has 2390/830 = 2.88x more calories than tofu per weight.

3.03L water/1kcal tofu = 0.33kcal/1L = 830kcal/2513L
1.82L water/1kcal whole chicken = 0.55kcal/1L = 2390kcal/4325L

Tofu takes 3.03/1.82 = 1.66x more water than chicken per calorie.
