3.2. Bioturbation Effects on Chemical Transport

Try these first

1. 1.

   What is bioturbation?

   Hint

   Think about organisms that interact with sediment.

2. 2.

   Name a type of organism involved in bioturbation.

   Hint

   Think of animals that live in the ground or sand.

3. 3.

   What is bioturbation?

   • A chemical process
   • The disturbance of sediments by organisms
   • A process of evaporation

   Hint

   Remember the role of organisms!

4. 4.

   True or False: Bioturbation has no effect on chemical transport.

   • True
   • False

   Hint

   Think about how organisms interact with sediments.

5. 5.

   Analyze how bioturbation in a coastal environment might differ from that in a riverine environment. Discuss the implications for sediment quality and contaminant movement.

   Hint

   Think about sediment types and their interactions with water.

6. 6.

   Design an experiment to measure the effects of bioturbation on contaminant release in a controlled laboratory setting. What variables would you consider?

   Hint

   Consider how to simulate natural conditions in your setup.
