Question

What is true for photolithotrophs ?

• A. Obtain energy from radiations and hydrogen from organic compounds
• B. Obtain energy from radiations and hydrogen from inorganic compounds
• C. Obtain energy from organic compounds
• D. Obtain energy from Inorganic compounds

Answer 1

The correct option is B Obtain energy from radiations and hydrogen from inorganic compounds

Photolithotrophs manufacture their own organic nutrients from inorganic raw materials $(H_2,O_2)$ with the help of radiation energy. Chemotrophs are organisms that obtain energy by the oxidation of electron donors in their environments. These molecules can be organic or inorganic.
