Final answer:
The percentage of solar energy incorporated into gross primary production varies depending on the ecosystem and can range from 0.01-6%. Factors like water and nutrient limitations can influence this efficiency. For example, a well-watered corn field might have an efficiency of 1.5%.
Step-by-step explanation:
The percentage of solar energy that is incorporated into gross primary production can vary depending on the ecosystem. In general, the efficiency of plants in converting sunlight into stored chemical energy is around 0.01-6%. However, the range can be influenced by factors like water and nutrient limitations. For example, a well-watered and fertilized corn field might reach 1.5% efficiency, while algae can have efficiencies of 5-6%. Dry climates with ample sunlight but little water may have lower efficiencies.
