Monod Equation - determines the limiting nutrient. Takes the growth rate of a population looks at concentration of nutrients. Graphed curves into equation. Different curves for different temperatures.
Carbon is the single most important nutrient for algae.
Coral reefs need higher pH - global warming kills corals by using the ocean as a CO2 sink and driving pH down. NO3 utilized by algae to create amino acids needed by animals. Phosphorus - Often limiting factor in fresh water. Phosphate, PO4 - form normally seen in freshwater systems and used by algae. A few years ago most detergents were phosphate based.
