Marine organisms like phytoplankton use dissolved CO₂ in ocean water for the process of __________.
Photosynthesis
Phytoplankton are microscopic, plant-like organisms that live near the surface of ocean water where sunlight can reach them.
Like land plants, they contain chlorophyll and use dissolved carbon dioxide along with sunlight and water to produce their own food.
This process, called photosynthesis, also releases oxygen and forms the base of the marine food chain.
Hence, the correct answer is photosynthesis.
