Question

Chemosynthetic bacteria are important producers of

• A. Areas around hydrothermal vents
• B. Ocean bed
• C. Lake bed
• D. Deltas

Answer 1

The correct option is A Areas around hydrothermal vents

Chemosynthesis is the biological conversion of one or more carbon containing molecules and nutrients into organic matter using the oxidation of inorganic compounds. Many chemosynthetic microorganisms are consumed by other organisms in the ocean, and symbiotic associations between chemosynthesizers and respiring heterotroph are quite common. Large populations of animals can be supported by chemosynthetic secondary production at hydrothermal vents, methane clathrates, cold seeps and isolated cave water.

So, option A is the correct option.
