Which statement describes the fact that pesticides move up the food chain?
Which statement describes the fact that pesticides move up the food chain?
The correct option is B Top predators often accumulate the pesticides contained in the bodies of their prey.
Top predators often accumulate the pesticides contained in the bodies of their prey. The following is an example showing how this occurs in nature: An anchovy eats zoo-plankton that have tiny amounts of mercury that the zoo-plankton has picked up from the water throughout the anchovies lifespan. A tuna eats many of these anchovies over its life, accumulating the mercury in each of those anchovies into its body. If the mercury stunts the growth of the anchovies, that tuna is required to eat more little fish to stay alive. Because there are more little fish being eaten, the mercury content is magnified.
