Document Summary
Q: which of the following groups of microorganisms is a guild: sulfate reducing bacteria, pseudomonads, actinobacteria, euryarchaeota. Marine environment: microbial life in the marine environment. Small cell size - increases efficiency of nutrient transport systems. High productivity nutrients come in from land that drain into the sea. Nh4 + energy: bacteria dominate in the photic zone (surface); archaea found at depth, as we go deeper, bacteria and archaea become equally abundant, one archaea"s role: oxidation of. Q: please explain why the small size of many marine pelagic bacteria is advantageous in the open ocean. Small size means that the ratio of cell surface area to cell volume is big enhancing interactions with the solutes in the environment and opportunities to obtain nutrients. No change in redox state - white reduced to fe 2+ state for iron. Iron exists as fe 3+ , which can be. Fe 0 = artificial; not a natural redox.
