Phytoplankton absorb carbon through the process of photosynthesis. Using sunlight, these microscopic organisms convert carbon dioxide and water into oxygen and glucose, which not only supports their own growth but also helps reduce carbon levels in the atmosphere. In Antarctica’s cold, nutrient-rich waters, phytoplankton thrive and play a vital role in the global carbon cycle, as they sequester carbon and prevent it from re-entering the atmosphere. This process makes phytoplankton essential in mitigating climate change, as they help regulate Earth’s carbon balance.
