Question

Primary productivity is defined as(1 point)the rate that plants and other photosynthetic organisms produce organic compounds.the process where green plants and some other organisms convert light energy into chemical energy using carbon dioxide and water.the overall amount of energy captured by plants and other photosynthetic organisms by the chloroplast.the adjusted amount of energy in an ecosystem due to energy use by organisms for respiration.

Answer 1

Correct answer: "the rate that plants and other photosynthetic organisms produce organic compounds."

Note: Gross primary productivity (GPP) is the total rate of production; net primary productivity (NPP) = GPP − respiration by the producers. The second option describes the process of photosynthesis, not the productivity rate.
