● The elevated temperature typically decreases the level of dissolved oxygen of water. Hence statement 1 is correct. ● This can harm aquatic animals such as fish, amphibians and other aquatic organisms. ● Thermal pollution may also increase the metabolic rate of aquatic animals, as enzyme activity, resulting in these organisms consuming more food in a shorter time than if their environment were not changed. ● Mixing of nutrients and oxygen in between water layers is very much dependent on water temperatures. ● The high temperature at the top layer prevents proper mixing of water. Hence statement 2 is correct. ● This can lead to increased bacteria levels when there is ample food supply. ● Many aquatic species will fail to reproduce at elevated temperatures
