Silver carp were introduced in the southeastern United States in the 1970s from their native habitat of China to control algal blooms that were occurring at aquaculture facilities and sewage lagoons. Silver carp escaped from captivity shortly after their introduction and are currently found as far north as North Dakota and Minnesota. Which of the following describes an unintended, negative consequence of the introduction of silver carp into the United States?
A) Silver carp decreased the amount of algae and aquatic vegetation in ponds and lagoons in the southern United States.
B) Silver carp populations in the United States are likely to become endangered as a result of limited prey resources in the new environment.
C) Silver carp became a keystone species and created more biodiversity in lakes and rivers in the southeastern United States.
D) Silver carp became an invasive species in the United States because their numbers were not being controlled by natural predators.
