Question 12

An invasive species is an animal, plant, or organism that has been intentionally or accidentally introduced into an ecosystem. The Asian carp is an invasive species that was introduced to the United States to help control the amounts of algae in ponds. They have since spread and overpopulated many ponds, rivers, and lakes. These Asian carp eat up to 40% of their body weight each day and are causing major problems for native fish. These filter feeding Asian carp eat large amounts of phytoplankton and zooplankton.
