NEETBotanyBiological Classification
Read the following statements regarding the classification and habitats of different bacteria and select the incorrect statement.
Options
- AMethanogens are a group of Eubacteria found in marshy areas and the gut of several ruminant animals.
- BHalophiles are Archaebacteria that are specially adapted to survive in extreme salty areas.
- CThermoacidophiles are Archaebacteria that can thrive in hot springs.
- DCyanobacteria are Eubacteria that can be found in freshwater, marine or terrestrial environments.
Correct answer
A. Methanogens are a group of Eubacteria found in marshy areas and the gut of several ruminant animals.
Step-by-step solution
The incorrect statement is that methanogens are Eubacteria. Methanogens, along with halophiles and thermoacidophiles, belong to the group Archaebacteria. Archaebacteria differ from Eubacteria (true bacteria) in having a different cell wall structure, which enables their survival in extreme conditions. Methanogens are found in marshy areas and the gut of ruminant animals where they produce biogas. Halophiles (found in salty areas) and thermoacidophiles (found in hot springs) are correctly classified as Archaebacteri
