Total rate of photosynthesis in a given area
WebThe productivity of an ecosystem refers to the rate of production or the amount of organic matter accumulated per unit area in unit time. Gross Primary Productivity (GPP) is referred as the total rate of photosynthesis including the organic matter used up in respiration during the measurement period. WebThrough photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.
