<span>biomes vary in their rates of net primary production-biomass that remains after cellular respiration limited by sunlight and nutrients available

The reason for this trend is that plants require sunlight, water, and temperatures warm enough to grow. This is true even in aquatic ecosystems, where sunlight and the availability of nutrients determine the level of net primary productivity.</span>
