Question

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

Accepted Answer

Chemolithotrophic mats primarily rely on oxidizing sulfur compounds for their energy generation. This is because sulfur compounds are abundant in their environment and can serve as electron donors in the absence of organic material.
