Question

A few gram seeds were placed in each of the three pots A, B and C containing soil. The soil in Pot A is mixed with some green twigs and leaves. The soil in pot B is mixed with old cow dung while soil of pot C is mixed with urea. Pots are watered regularly. Which of the following will be observed after 10 days?

• A. Lot of growth in pot A
• B. Not much growth in pot B and a lot of growth in pot A
• C. Lot of growth in pot B but very little growth in pot C
• D. Very little growth in pot A but a lot of growth in pots B and C

Answer 1

The correct option is D

Very little growth in pot A but a lot of growth in pots B and C

Very little growth in pot A but a lot of growth in pots B and C because pots B and C have a good amount of nutrients in their soil in the form of manure and fertilizers. When turned into compost and fed to plants and vegetables, cow dung becomes a nutrient-rich manure and also fertilizers like urea can enrich the soil with nitrogen.
