In a local river, a new industrial plant has been increasing the temperature of the water with thermal pollution. The average water temperature increased by 2 degrees Fahrenheit in but has not changed since then.
Which explanation BEST predicts how this change will affect the local fish population in the river?
А
The fish population will stay the same, because the change in water temperature is too small to have an impact.
B
The fish population will increase, because fish reproduce more in warmer temperatures.
С
The fish population will decrease because the pollution will make the water more acidic.
D
The fish population will decrease, because there will be less oxygen in the water.
