Challenge Problems
Push your limits with advanced challenges
You conduct an experiment to compare chemical concentrations in sediments with and without bioturbators introduced. Discuss the potential results and the mechanism behind these observations.
💡 Hint: Consider the roles of burrowing, egestion, and porosity.
