This graph shows the sources of the nitrogen entering the Gulf of Mexico as pollution. What is one conclusion you can make based on the information in the graph?

• Nitrogen that comes from the atmosphere is more harmful than nitrogen that comes from crops.

• Most nitrogen pollution found in the Gulf of Mexico comes from farming crops.

• Corn and soybeans are the only crops associated with nitrogen pollution.

• Nitrogen is not a problem in the Gulf of Mexico.

The diagram below shows the relationship between some of the organisms in a marine food web. Which of the following is MOST LIKELY to happen if a large number of phytoplankton are killed from runoff entering the ocean?

• The number of porpoises would probably stay the same because porpoises are far removed from phytoplankton in the food web

• The number of zooplankton would probably increase because they wouldn’t have to compete with phytoplankton for food.

• The number of salmon would probably decrease because there would be less food available for zooplankton and herring.

• The Sun would probably not emit as much energy because there would not be as many phytoplankton in the ocean.
