Suppose That You Compare the Amount of Food Needed by Four

Suppose that you compare the amount of food needed by four groups of lizards, each of which has an MR that is expected for its body size. There are 10 lizards weighing 10 g each, 5 lizards weighing 20 g each, 2 lizards weighing 50 g each, and a single 100-g lizard. Assuming equivalent digestions, similar food, and so on, which lizard group requires the most food?

A) The 10-g lizard group
B) The 20-g lizard group
C) The 100-g lizard
D) All lizard groups require the same amount of food.
