Which of the following statements about metabolic rate is false? metabolic rate may be measured by determining the rate of oxygen consumption. the metabolic rate per gram of tissue in ectotherms is dependent on external temperature. an organism's overall metabolic rate increases with the animal's mass. the metabolic rate per gram of tissue is greater in endotherms than in ectotherms. the metabolic rate per gram of tissue is greater in large endotherms than in small endotherms.

The metabolic rate per gram of tissue is greater in large endotherms than in small endotherms.

Explanation:

Metabolic rate is a measurement of metabolism in animals: how much energy is used per time. Energy used on a daily level is described as basal metabolic rate. Among both, endotherms (maintain their own heat) and ectoterms (depend on external heat) metabolic rate depends on animal's activity, active animals have higher metabolic rate.

Metabolic rate in ectoterms vary with temperature, while in endoterms it does not.

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
