Which metabolic strategy is MOST common in chemolithotrophic mats?
A) ammonia oxidation
B) iron oxidation
C) nitrate reduction
D) sulfur oxidation

Question

Quizplus · Accepted Answer

Chemolithotrophic mats are often found in environments where oxygen is scarce, such as hydrothermal vents or deep sea sediments. In these environments, sulfur compounds are typically abundant and can serve as a source of energy for chemolithotrophs. Therefore, sulfur oxidation is the most common metabolic strategy in chemolithotrophic mats. Ammonia oxidation is more common in certain types of soils and nitrogen-rich aquatic environments, while iron oxidation and nitrate reduction are less common in chemolithotrophic mats.
