Show transcribed image text Fertilizer input often increases terrestrial NPP. What is the mechanism responsible for this? It increases algal density, thereby adding ecosystem photosynthesis. It increases the Rubisco concentration in leaves, which makes higher photosynthetic rates possible. It allows plants to grow more squareroots, thereby making water uptake less limiting. It increases plant biodiversity, so that fast-growing species can produce more biomass.
