Bioaccumulation Lesson

What is bioaccumulation in food chains?

• The process of removing substances from an organism over time.

• The build up of toxic substances in an organism over time.

• The movement of organisms from one place to another

• The breakdown of substances in an organism over time.

How do toxic substances enter food chains?

• Toxic substances enter food chains through the natural growth process of plants and animals

• Toxic substances enter food chains through direct injection by humans

• Through air, water, and soil contamination, as well as through the eating contaminated plants and animals.

How does bioaccumulation in food chains impact human health?

• It only affects the health of animals in the food chain

• It reduces the risk of human exposure to harmful substances

• It has no impact on human health

• It can lead to the accumulation of harmful substances in the tissues of organisms, which can then be passed on to humans through consumption of contaminated food.
