D Correct answer
Explanation

Small birds with extremely high metabolic rates, such as hummingbirds and chickadees, must consume approximately twice their body weight daily. This massive food intake is necessary to fuel their rapid metabolism and maintain their energy levels. Options like 10%, half, or equal to are insufficient for their energy needs.
