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.

A small marine area has phytoplankton as its only producer.  Should the marine biologist be concerned about this ecosystem?

• No the fish do not need the phytoplanton. Since there are so many fish, there is high biodiversity.
• Yes, this ecosystem has low biodiversity.  Without a producer the herbivores will die out leaving no food.
• Yes, this system has high biodiversity; however the fish can adapt and get food from another source.
• Yes, the fish will overate to get all of the phytoplankton that is left, then they will die.
