Primary productivity refers to the rate at which energy is converted by photosynthetic and chemosynthetic autotrophs to organic substances. Therefore, the correct answer from your options would be:

**d. the rate at which energy is stored by plants.**

This refers to the process of photosynthesis, where plants convert solar energy into chemical energy stored in glucose and other organic compounds.
