What happens to dissolved oxygen levels as temperatures increase?

As temperatures increase, the solubility of oxygen in water decreases. This is because warmer water molecules have more kinetic energy, which causes them to move more rapidly and reduces the ability of the water to hold dissolved gases like oxygen. Consequently, as temperature rises, the amount of dissolved oxygen available for aquatic life decreases, leading to potential challenges for fish and other organisms that rely on oxygen for survival. This relationship between temperature and dissolved oxygen is critical in aquatic ecosystems, and understanding it is essential for managing water quality and protecting biodiversity.
