Question Amit and Sumit studied different kinds of microbes like viruses, bacteria, algae, fungi and protozoa. Which of the following statements does not match with the characteristic features of fungi ?
- Fungi may be unicellular or multicellular.
- They do not have chlorophyll and cannot prepare their own food.
- Fungi help in biological nitrogen fixation and improve the soil fertility.
- They are saprophytic in nature.
Fungi help in biological nitrogen fixation and improve the soil fertility.
Reason — Fungi are saprophytic in nature, i.e. they feed on dead and decaying organic matter and are called the natural cleaners of environment. They do improve soil health through decomposition but not by fixing nitrogen directly.
