Why should chemoautolithotrophic sulfur oxidizers and green
sulfur bacteria be unlikely to compete for H2S? 1. Oxygen is
required by one and toxic to the other 2. Green sulfur bacteria
live symbiotically with plants 3. CO2 is likely to limit carbon
fixation, not H2S 4. They have adapted to using different
wavelengths of light
