Sediment (soil particles) in natural waters can

Question

Quizplus · Accepted Answer

Sediment, which consists of soil particles, in natural waters can have several negative effects on the aquatic environment and human activities. These effects include:
a. Reduce photosynthesis by blocking light: Sediment can cloud the water, reducing the penetration of sunlight. This can inhibit the growth of aquatic plants and algae that require sunlight to perform photosynthesis. When photosynthesis is reduced, it can lead to a decrease in oxygen production and affect the overall health of the aquatic ecosystem.
b. Reduce fish populations by clogging gills: Sediment can also affect fish populations by clogging their gills. Fish rely on their gills to extract oxygen from the water, and when these become clogged with sediment, it can lead to respiratory stress or even death. Additionally, sediment can smother fish eggs and larvae, reducing reproductive success.
c. Increase the cost of producing drinking water: When sediment enters water treatment facilities, it can increase the complexity and cost of the water purification process. Treatment plants must remove the sediment to ensure the water meets safety standards for human consumption. This additional treatment process can lead to higher costs for water production.
Therefore, the correct answer is:
d. All of these: Sediment in natural waters can reduce photosynthesis by blocking light, reduce fish populations by clogging gills, and increase the cost of producing drinking water.
