Answer:
This is biomagnification, and it means that higher-level predators-fish, birds, and marine mammals-build up greater and more dangerous amounts of toxic materials than animals lower on the food chain. In this activity you will explore the biomaginification of toxic chemical, mercury, through a simple marine food chain.
