5.1. Anaerobic Reactions Overview

Try these first

1. 1.

   What is diffusion?

   Hint

   Think about how a drop of food coloring behaves in water.

2. 2.

   Name one organism that contributes to bioturbation.

   Hint

   Consider animals that live in the sediment.

3. 3.

   What is the main mechanism by which contaminants move from sediments to water?

   • Bioturbation
   • Diffusion
   • Evaporation

   Hint

   Think of how substances mix in liquids.

4. 4.

   True or False: Bioturbation can negatively affect water quality by mixing contaminated sediments.

   • True
   • False

   Hint

   Consider the impact of living organisms on still sediments.

5. 5.

   Design an experiment to measure the effect of bioturbation on contaminant transport in a controlled sediment environment.

   Hint

   Think about creating a setup that isolates the variables.

6. 6.

   Analyze a real-world scenario in which sediment disturbance from construction could impact local water quality. Suggest mitigation strategies.

   Hint

   Assess how construction affects nearby aquatic systems.
