Which outcome results when a fish's lamellae in the gills collapse due to sediment exposure?

💡 Explanation

When lamellae collapse, the surface area for gas exchange decreases because diffusion distance increases leading to reduced oxygen absorption. Therefore, reduced oxygen uptake occurs, rather than increased carbon dioxide removal, nutrient absorption, or osmoregulation which entail separate processes.
