A coastal region experiences algal blooms and coral bleaching after unusually high global temperatures. Which interaction between Earth's spheres best explains this effect?
Ocean warming lowers CO2 absorption and stresses marine life
Rising global temperatures warm ocean water, which reduces its capacity to absorb and hold dissolved gases such as carbon dioxide.
This warming stresses corals, causing them to expel the symbiotic algae living in their tissues, which leads to coral bleaching, while nutrient imbalance can also trigger algal blooms.
Hence, ocean warming lowers CO2 absorption and stresses marine life.
