If a toxic chemical was introduced into the producers it would kill off a lot of the primary and secondary consumers. It would make it to the Amur Leopard but not hurt it as much. When the Primary and secondary things die off it will affect the Leopard because they are its main source of food. When the Amur Leopard doesn't have food it will have to leave and go to a different biome that will support it. Even though bioaccumulation will occur it will not effect the Leopard. Though through biomagnification it will severely hurt the lower species in the food web.
