• 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.

What are the effects of bioaccumulation on top predators in a food chain?

• No impact

• Problems with the organism's health

• Increased life expectancy

How do toxic substances affect the organisms at lower trophic levels in a food chain?
