Acid deposition has caused nitrogen levels in a lake to increase by nearly 50 percent due to the increase in pollution output from local industries. How will the lake be affected by the increase of nitrogen? (5 points) Algal populations will increase dramatically, crowding out and reducing resources for other organisms.
Mercury levels will rise, and the number of toxic fish will increase until the algae die.
Once the algae die, the pH level will be neutral and terrestrial organisms can drink from the lake again.
Nitrogen levels will be reduced when the coal-burning power plant is built and up and running.
