Which of the following factors does not affect the distribution of organisms in an aquatic habitat?
Answer Details
The factor that does not affect the distribution of organisms in an aquatic habitat is "humidity." Humidity is a measure of the amount of water vapor in the air, which is not a relevant factor in aquatic environments. The other factors listed can affect the distribution of aquatic organisms.
- Turbidity: the measure of how clear or cloudy the water is, which affects the penetration of light and the photosynthetic activity of aquatic plants.
- Depth of water: affects the amount of light and temperature, and the types of organisms that can survive in a particular depth range.
- Temperature: affects the metabolic rate of aquatic organisms, and the rate of chemical reactions in the water.
- Availability of nutrients: affects the growth and reproduction of aquatic plants and algae, which form the base of the aquatic food chain.
