D. through the process of desalination
A. through the process of photosynthesis
Seaweed and algae play a crucial role in combating ocean acidification and climate change through the process of photosynthesis. During photosynthesis, these photosynthetic organisms take in carbon dioxide from the water and atmosphere and convert it into organic matter, releasing oxygen as a byproduct. This helps reduce the levels of carbon dioxide in the water, which in turn helps mitigate ocean acidification and climate change. Additionally, the organic matter produced by seaweed and algae can be stored in ocean sediments, further helping to remove carbon dioxide from the atmosphere.
