Question

Quizplus · Accepted Answer

Anaerobic bacteria are able to thrive in environments that lack free oxygen. This is because they are able to use alternate electron acceptors such as nitrate or sulfate in place of oxygen for cellular respiration. Aerobic bacteria require oxygen for respiration and photosynthetic bacteria use sunlight as a source of energy, so neither of these options would be correct. Placental is not a type of bacteria and foraminifera are unicellular aquatic organisms, not bacteria.
