In August 2010, the Asian clam was discovered in Lake George. It is not native to that area. A single clam can reproduce and release hundreds of offspring in a day. Fish and crayfish eat the clams but cannot keep pace with the rate at which the clams reproduce. The introduction of the Asian clam into Lake George is * 3 points A positive, because it adds to the stability of the ecosystem B positive, because the fish and crayfish would otherwise not have food C negative, because it decreases water pollution in the lake D negative, because it competes with native clam species and reduces stability
