Solar energy is the ultimate source of energy for all ecosystems. It is captured by autotrophs (producers) through photosynthesis. Also, net primary productivity (NPP) is the rate at which producers store energy in the form of organic matter after using some for respiration. Thus, both statements are factually correct.

Hence, the correct answer is Option (2) Both statement I and statement II are correct
