Which genus would you MOST likely find in the photic layer of the oceans due to its abundance and aerobic chemoorganotroph phenotype?
A) Acetobacter
B) Nitrosomonas
C) Paracoccus
D) Pelagibacter

Question

Quizplus · Accepted Answer

Pelagibacter is a common marine bacterium found in the photic layer of the oceans. It is a chemoorganotroph, meaning it obtains energy from organic compounds, and is also aerobic, requiring oxygen for respiration. Nitrosomonas and Paracoccus are also bacteria commonly found in aquatic environments, but they are not as abundant in the photic layer as Pelagibacter. Acetobacter, on the other hand, is more commonly found in terrestrial environments and is not typically associated with oceanic habitats.
