Question

select the wrong statement about chemoautotrophic bacteria.
1) they do not have photosynthetic pigment
2) they use light as energy source for synthesizing food
3) they oxidise certain inorganic substance
4) they play a great role in recycling of nutrients like nitrogen​

Answer 1

Answer:

Chemotrophs are a class of organisms that obtain their energy through the oxidation of inorganic molecules, such as iron and magnesium. The most common type of chemotrophic organisms are prokaryotic and include both bacteria and fungi. All of these organisms require carbon to survive and reproduce. The ability of chemotrophs to produce their own organic or carbon-containing molecules differentiates these organisms into two different classifications–chemoautotrophs and chemoheterotrophs

Answer 2

2) they use light as energy source for synthesizing food is correct answer.

• Light energy is used as source by the photosynthetic organisms. They use light energy in the form of solar energy.
• Chemotrophic organisms are the organisms that derive energy from the chemical reaction. They derive energy by oxidation of compounds.
• The compounds or molecules can be organic or inorganic in nature.
