Biomagnification and Bioaccumulation

Pesticides and herbicides eventually show up in higher-level consumers (i.e. as you go up the food chain) due to (a)  

• biomagnification

• climate change

• habitat destruction

• bioaccumulation

Toxin concentrations (a)   as you go up the food chain.

• do not change

• increase

• decrease

When you consume an organism, you only receive 10% of the energy, but how much of the toxins do you receive? (a)  

• All of the toxins

• 10% toxins

• 1% toxins

• None of the toxins

In biomagnification, the amount of toxin

• decreases in concentration along the food chain

• remains the same along the food chain

• increases along the food chain

Which of the following best describes biomagnification?

• The increase in toxin concentration as it moves up the food chain

• The decrease in toxin concentration as it moves up the food chain

• The constant level of toxin concentration in the food chain

• The elimination of toxins in the food chain

Bioaccumulation occurs when:

• An organism absorbs toxins faster than it can eliminate them

• Toxins are broken down by organisms

• Toxins are evenly distributed in the environment

• Toxins are only present in water
