Study Notes
Harmful Substances in Food Chains
- Harmful substances, such as pesticides, can accumulate in the bodies of living organisms in a food chain, causing harm to the entire ecosystem.
- The potential impact of harmful substances in food chains is bioaccumulation, biomagnification, and eventually, harm to humans and the environment.
- Harmful substances can alter the growth, development, and reproduction of living things in food chains, and even cause death.
Transfer Mechanism and Movement
- The primary transfer mechanism for harmful substances in food chains is through consumption, where one organism eats another, transferring the harmful substances up the food chain.
- Harmful substances, not energy, move through food chains, accumulating in higher trophic levels.
- As they move through food chains, harmful substances increase in concentration, causing greater harm to organisms at higher trophic levels.
