Solution
The correct option is B Primary productivity
Primary productivity is the amount of energy captured by primary producers during photosynthesis on a square meter of land each year. Autotrophic organisms are often primary producers in their ecosystems. They acquire their useful free energy from sources other than food: either from the energy of sunlight (photoautotrophs) or from oxidative chemical reactions (chemoautotrophs). Autotrophic organisms (chemosynthetic and photosynthetic bacteria, algae, and plants) are primary producers.
