In wetlands, Beggiatoa bacteria oxidize H2S for energy. Removal of H2S enables growth of other microbes for which H2S is toxic. However, Beggiatoa derives no benefit from these microbes. This interaction is an example of:

A) syntrophy B) mutualism C) commensalism D) amensalism E) synergism A) syntrophy B) mutualism C) commensalism D) amensalism E) synergism
