    1. If a bacteriophage quickly kills a bacterium it has infected, it is an example of parasitism or predation and why?
    2. What is a microbial community? How could bacteriophages alter the composition of a bacterial community?
    3. If use of a critical resource by one group of microbes cuts off the supply of that resource to another, what is the name of the interaction?
    4. How is syntrophy distinct from mutualism?
    5. Is oxygen depletion by nitrifiers beneficial to anammox microorganisms?
    6. How can abiotic iron reduction by sulfide oxidation lead to growth of other sulfur cyclers?
    7. Imagine two environments, A and B. In environment A, iron reducers transfer electrons to ferric minerals. In environment B, iron reducers share electrons with methanogens through interspecies electron transfer. How would you expect the chemistry of the environments to differ?
