Question

Quizplus · Accepted Answer

While carbon dioxide (CO₂) is an important molecule for photosynthesis and thus the production of energy for many organisms, a CO₂-rich atmosphere is not required for life on Earth. In fact, the atmosphere of primordial Earth likely contained minimal amounts of CO₂, and the evolution of photosynthesis led to an increase in atmospheric oxygen (O₂) and a decrease in CO₂.
