Which of the following factors may not affect living organisms in an aquatic habitat?

Humidity may not affect living organisms in an aquatic habitat. Humidity refers to the amount of moisture in the air, which is not relevant in an aquatic habitat where the organisms are surrounded by water. Turbidity, temperature, and light are all important factors that can affect living organisms in an aquatic habitat. Turbidity refers to the clarity of the water, which can affect the penetration of light and the ability of organisms to find food. Temperature is important because it can affect the metabolic rates of organisms and their ability to survive. Light is important for photosynthetic organisms and for visual communication and orientation in many species.
