A team of scientists studying a kelp forest ecosystem noticed a sudden decrease in the kelp population. They discovered that a foreign species with no natural predators in the ecosystem was eating the kelp. The scientists hypothesized that ships from other parts of the world had transported the foreign species to this ecosystem. The food web below shows the relationship between the organisms in the kelp forest ecosystem.

• Use the relationships in the food web to discuss whether the scientists should be concerned about the effect of the new species on the ecosystem.
• Be sure to include in your discussion how the new species will affect each of the other organisms in the food web.
