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.
