Why might chemosynthetic communities exist only in places like the deep-ocean floor rather than across a wide range of land and sea habitats, the way photosynthesis-based communities are?
Chemolithrophs near hydrothermal vents support a variety of other life forms there. Explain now their role is analogous to that of photosynthetic organisms in the terrestrial environment.
Why might H2 metabolism have evolved as amechanism for energy conservation in the earliestorganisms on Earth?
