Which mechanism limits coral growth under high phosphate conditions?

💡 Explanation

High phosphate reduces coral growth because phosphate competitively inhibits nitrate uptake, which blocks nitrogen fixation necessary for zooxanthellae photosynthesis; therefore growth is stunted, rather than enhanced photosynthesis or calcification increases, since both depend on algal symbionts.
