Which phenomenon limits phytoplankton growth during deep coastal upwelling events?

💡 Explanation

When deep water upwells, it brings nutrients to the surface but rising from deeper implies diminished radiance because light absorption follows exponential decay, limiting photosynthetic activity in phytoplankton. Therefore insufficient light restricts growth, rather than nutrient depletion, wind mixing, or predation, which are less direct constraints.
