Solution

The correct option is D Chemosynthetic bacteria
Primary producers of the deep sea hydrothermal vent ecosystem are chemosynthetic bacteria. Sulfide-oxidizing bacteria are chemolithotrophic in nature. They are found in the deep sea hydrothermal vent ecosystem. They provide the primary food for the invertebrates found in the immediate vicinity of the vent ecosystem.
Thus, the correct answer is option C.
