Which increased metabolic demand occurs when fish maintain osmoregulation?

💡 Explanation

Increased ion transport directly increases fish metabolic needs because active transport requires energy to pump ions against their concentration gradients in osmoregulation rather than letting them diffuse freely; therefore, active transport is used rather than passive because needed blood concentrations might vary.
