When fertilizers run off farmland into streams and ponds, the nitrogen content of the water increases. This can lead to rapid growth of algae in a process called eutrophication. How can this process affect other organisms in the water?

• Oxygen is used up as algae is decomposed, reducing the amount available to other organisms.
• The water becomes better able to support aerobic organisms.
• The algae provide food for fishes and other organisms, leading to decreased algae populations.
• The extra nitrogen provides additional food for the other organisms, increasing their population.
