The correct answer is:

decreased oxygen in the water

Answer 3

Yes, the answer is correct. Algae blooms can lead to a decrease in oxygen levels in the water, which can have detrimental effects on marine life. When algae blooms die and decompose, bacteria consume the oxygen in the water during the decomposition process, leading to low oxygen levels (hypoxia) or even anoxic conditions. This can suffocate or kill fish, shellfish, and other organisms that rely on oxygen to survive.
