How does acid rain affect aquatic plants?

I'm doing some coursework for environmental science with the aim of investigating how acid rain concentration affects aquatic plants such as water marigold. I just need to know why acid rain results in the stunted growth. What does the acid do to the plant or the water to kill it?


Any answers would be greatly appreciated


Thanks

It helps plants grow.
Reply:acid dissolves the nutrients they really need like calcium, magnesium and potassium so their growth is stunted. plankton eat this and when there is too much they die.
