Question

Which of the following is a type of Chemoautotroph

• A. Sulphur bacteria, Beggiatoa thiobacillus
• B. Iron bacteria, Ferrobacillus
• C. Leptohrix
• D. All of the above

Answer 1

The correct option is D All of the above

Chemoautotrophs are organisms that derive their energy from the oxidation or breakdown of various inorganic or organic food substances in their environment. The process releases energy which supports metabolic activity in the organism. One example of a chemoautotroph would be iron bacteria (Thiobacillus ferrooxidans). Another example of a chemoautotroph would be sulfur bacteria (Thiobacillus Thiooxidans). Sulphur bacteria live mainly in pyrite deposits.

So, the correct option is 'All of the above'.
