Question 33

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?

Accepted Answer

Oxygen is used up as algae is decomposed, reducing the amount available to other organisms.

Answer

The water becomes better able to support aerobic organisms.

Answer

The algae provide food for fishes and other organisms, leading to decreased algae populations.

Answer

The extra nitrogen provides additional food for the other organisms, increasing their population.
