Answer: A. Archaea

Domain Archaea is the group of single celled prokaryotic organisms. These organisms lack a well defined nucleus and cell organelles.

These organisms are tolerant to saline conditions and they survive in marshes, hence they are called as halophiles.  They produce methane as a metabolic byproduct, therefore are called as methanogens.

Here green algae comes under autotrophs(prepares their own food), periwinkle and microscopic animals are herbivores(depend on producer); mussel, barnacle, dogwhelk and crab are carnivores(depend on herbivore); dogfish is an omnivore(depends on both producer and carnivore).
