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

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