TEXT FOR QUESTION: Prochlorococcus is a bacterium that lives in marine environments and produces hydrogen peroxide as a byproduct of its biological processes. Hydrogen peroxide is toxic to Prochlorococcus. Another marine bacterium, called Alteromonas, produces an enzyme that breaks down the hydrogen peroxide as a result of normal metabolism. This prevents both organisms from being harmed.
Based on the information above, address the following questions:
What are the two relationships that could exist between Prochlorococcus and Alteromonas?
What additional information would be required to determine which of the two relationships exist between Prochlorococcus and Alteromonas?
Read the question carefully. Then enter your answer in the box provided.
