Which mechanism facilitates coral reef nutrient uptake when exposed to increased ocean acidity?

A)Enhanced denitrification by symbiotic bacteria
B)Reduced phosphate availability for zooxanthellae
C)Ammonia absorption by the coral host
D)Increased nitrogen fixation by cyanobacteria

💡 Explanation

Enhanced denitrification reduces excess nitrogen inputs when ocean acidification stresses coral; this symbiotic denitrification process helps maintain nutrient balance, therefore reducing harmful algal blooms, rather than exacerbating them like other choices.
