The correct answer is:
C. They add oxygen to and remove carbon dioxide from the atmosphere.
Phytoplankton perform photosynthesis, which entails using sunlight to convert carbon dioxide and water into glucose and oxygen. As a result, they consume carbon dioxide and release oxygen, playing a crucial role in the Earth's carbon and oxygen cycles.
