Options
- AGreen algae
- BChemosynthetic bacteria
- CBlue-green algae
- DCoral reefs
Correct answer
B. Chemosynthetic bacteria
Step-by-step solution
The primary producers of the deep-sea hydrothermal vent ecosystem are Archaebacteria, they have a chemosynthetic mode of nutrition. In most of the animals, the metabolic reactions or entire physiological functions proceed optimally in a narrow temperature range. In humans, it occurs at 37 o C temperature. However, there are microbes like Archaebacteria that flourish in hot springs and deep-sea hydrothermal vents where temperatures far exceed 100 o C. Archaebacteria sustain their life under extremes of temperature a
