← Nature & AnimalsWhich respiratory consequence results when sudden water temperature increase impairs the swim bladder function in fish?
A)Decreased oxygen uptake efficiency✓
B)Increased carbon dioxide retention
C)Disrupted ion transport equilibrium
D)Elevated metabolic rate causing acidosis
💡 Explanation
When water temperature increases, the partial pressure of dissolved gases changes and the swim bladder's ability to regulate buoyancy by controlling gas diffusion is affected which reduces efficient oxygen diffusion across gills. Therefore, decreased oxygen uptake occurs, rather than increased CO2 retention, disrupted transport, or acidosis which involve different physiological and environmental triggers.
