Name the organisms which do not derive energy directly or indirectly from the sun

• A. Chemosynthetic bacteria
• B. Pathogenic bacteria
• C. Symbiotic bacteria
• D. Mould

Answer 1

The correct option is A Chemosynthetic bacteria

Chemosynthetic bacteria do not need sunlight to grow because they prepare their food without the help of light. They use inorganic molecules as a source of energy and convert into organic substances. They obtain energy from the oxidation of organic substances.

Photosynthetic bacteria and plants-derive energy directly from the sun.

Thus, the correct answer is 'Chemosynthetic bacteria.'
