Question

water from nearby rivers or lakes is usually used to cool down the reactors in nuclear power plants. the release of this heated water back into the river or lake would most likely result in a decrease in the amount of sunlight necessary for photosynthesis in the water a change in the number of mutations in plants growing near the water a reduction in biodiversity due to thermal stress an increase in the sewage content in the water

Explanation:

Thermal pollution from heated water release can cause thermal stress on aquatic organisms. This stress often leads to a reduction in biodiversity as many species are sensitive to temperature changes.

Answer:

a reduction in biodiversity due to thermal stress
