Answer 1

To measure primary productivity in an ecosystem, **carbon dioxide consumption** is typically used. This is because primary productivity refers to the rate at which living organisms, particularly plants and phytoplankton, convert carbon dioxide into organic compounds through photosynthesis. Thus, the most appropriate response is **carbon dioxide consumption**.
