Which of the following is NOT a contributing factor to HABs?

Harmful algal blooms are driven by conditions that fuel rapid phytoplankton growth: abundant nutrients fuel cell production, sunlight provides the energy for photosynthesis, and warm water speeds metabolic rates and reproduction. Excess phosphorus or nitrogen directly feeds algal growth, while sunlight is essential for photosynthesis, and warm temperatures (often above 25°C) help blooms develop faster. High salinity, however, is not a universal driver of HABs. Blooms can occur in freshwater, brackish, and marine waters with a range of salinities, and salinity alone does not typically trigger bloom formation. So, high salinity is not a contributing factor, making it the correct choice.
