|---|---|
| Microbes | Relationships |
| A. Bacillus thuringiensis | I. Butterfly caterpillar |
| B. Nucleopolyhedrovirus | II. Biofertiliser |
| C. Anabaena | III. Baculoviruses |
| D. Methanobacterium | IV. Anaerobic sludge |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A-I, B-III, C-II, D-IV
(A) Bacillus thuringiensis — this matches (I) Butterfly caterpillar. Dried spores of Bt are sprayed on plants. When a caterpillar eats them, the toxin is released in its gut and kills it.
(B) Nucleopolyhedrovirus — this matches (III) Baculoviruses. Nucleopolyhedrovirus is a genus of baculoviruses. These viruses attack insects and are used as species-specific biocontrol agents.
(C) Anabaena — this matches (II) Biofertiliser. Anabaena is a cyanobacterium. It fixes atmospheric nitrogen and adds it to the soil of paddy fields.
(D) Methanobacterium — this matches (IV) Anaerobic sludge. It grows without oxygen in the anaerobic sludge of sewage treatment. There it produces methane, the main gas of biogas.
