2.2.6—Cellular respiration question 1
Figure:Coastal seawater temperature near a nuclear power station
the temperature profile shown above below shows a range of coastal seawater temperatures at different distances from a nuclear power station. Nuclear power stations may be responsible for localized thermal pollution of coastal waters. Thermal pollution is caused by warmer water being released into a colder body of water.
Thermal pollution lowers the dissolved oxygen content of water. Suggest the effect of this on a named transformation process.
