NEETBotanyBiological Classification
Identify the incorrect statement among the following.
Options
- AChemosynthetic autotrophic bacteria play a great role in recycling nutrients like nitrogen, phosphorous, iron
- BArchaebacteria differ from other bacteria in having a different cell wall structure.
- CMycoplasma are organisms that completely lack a cell wall and can survive without oxygen.
- DHeterotrophic bacteria are less abundant in nature as compared to autotrophic bacteria.
Correct answer
D. Heterotrophic bacteria are less abundant in nature as compared to autotrophic bacteria.
Step-by-step solution
Heterotrophic bacteria are the most abundant in nature, with the majority of them being important decomposers. Therefore, the statement claiming they are less abundant than autotrophic bacteria is incorrect. Chemosynthetic autotrophic bacteria oxidise various inorganic substances and play a great role in recycling nutrients. Archaebacteria have a unique cell wall structure that allows them to survive in extreme conditions. Mycoplasma completely lack a cell wall and are capable of surviving without oxygen. Answer: H
