उत्तर
(i) - (c), (ii) - (d), (iii) - (b), (iv) - (a)
Explanation:
| Column-A | Column-B | ||
| (i) | Lady bird beetle | (c) | Aphids |
| (ii) | Mycorrhiza | (d) | Glomus |
| (iii) | Biological control | (b) | Trichoderma |
| (iv) | Biogas | (a) | Methanobacterium |
Aphids are frequent plant pests that are naturally preyed upon by ladybird beetles. A symbiotic relationship between fungi and plant roots is known as mycorrhiza. One common mycorrhizal fungus that aids in plant nutrient absorption is the species Glomus. A fungus called Trichoderma is employed as a biocontrol agent to inhibit plant diseases. Methanobacterium is a methanogenic bacterium that produces methane and is necessary for the production of biogas in anaerobic digesters.
