The metabolic rate of both organisms would remain unchanged.

The metabolic rate of the ectothermic organism would increase, and the metabolic rate of the endothermic organism would decrease.

The metabolic rate of the ectothermic organism would increase, and the metabolic rate of the endothermic organism would remain unchanged.
