Which of the following best describes how thermal pollution from power plants can affect aquatic ecosystems?
~Water injected into the ground during the hydraulic fracking process can seep into wells, causing methane contamination.
~Warm water runoff that reaches lakes and ponds slows down the metabolic rate of aquatic animals, which decreases primary productivity.
~Warm water discharged into rivers and streams decreases the oxygen content of the water, which reduces the number of fish species.
~Wastewater from nuclear power plants contains radioisotopes and carbonic acid, which increase the rate of cancer in aquatic species.
