APFIVE The metabolic rate ($$B$$) of an organism is related to its body mass ($$M$$) by the power-law equation $$B = kM^{3/4}$$. Which of the following conclusions is best supported by this relationship?
The equation shows that as body mass increases, the metabolic rate increases at a slower rate than mass, meaning larger animals have a lower metabolic rate per unit mass.
The direct proportionality between metabolic rate and body mass implies that all organisms, regardless of size, expend energy at the same rate per unit mass.
Since the exponent 3/4 is greater than 1, larger organisms must have a higher metabolic rate per unit mass compared to smaller organisms.
The relationship indicates that metabolism is not influenced by body mass, thereby ensuring a uniform energy expenditure across all sizes.
