← Nature & AnimalsWhich outcome reduces the reef's calcification rate following coral bleaching?
A)Increased ROS from impaired photosynthesis✓
B)Enhanced nutrient absorption from seawater
C)Decreased symbiont population density
D)Elevated zooxanthellae photosynthetic efficiency
💡 Explanation
Increased ROS triggers the destruction of the coral tissue because the damaged zooxanthellae cause elevated oxidative stress, impairing energy provision. Therefore, calcificiation slows due to energy constraints, rather than efficient photosynthesis that would elevate energy reserves.
