Question

which of the following is a factor that affects the amount of dissolved oxygen in water? the number of predators the waters temperature the waters color the ph level of the water

Explanation:

The solubility of gases (including oxygen) in water is affected by temperature. As temperature increases, the solubility of oxygen in water decreases. Predators affect the ecosystem but not directly the amount of dissolved oxygen. Water's color and pH level do not have a direct impact on the amount of dissolved oxygen compared to temperature.

Answer:

the water's temperature
