    What does this mean? 'Primary productivity is the total amount of energy fixed by photosynthesis. It is the net flux of carbon from the atmosphere to plants, per unit time. It is a rate and may be measured in terms of energy per unit time, such as MJ m-2 yr-1'. What are they measuring exactly? The rate at which carbon dioxide diffuses into the plant? Or the rate at which carbon dioxide is converted to glucose? Or neither?

    Actually I think I understand, they're measuring the amount of carbon that enters the plants over a certain period of time, as the amount of carbon can indicate the amount of energy present. Which can then be stored in the glucose during photosynthesis. Am I right?
