Which consequence occurs when a fish expends excessive energy maintaining internal salt balance?

💡 Explanation

Higher energy use will occur because excessive salt maintenance raises cellular ion gradients; therefore, metabolic activity increases for osmoregulation, rather than benefits such as countercurrent exchange improvements which would require altered gill structure or physiology.
