Answer 1

Solution:


Natural pest controlling methods include using organic oils, genetically modified organisms, various agricultural methods, etc. [1 Mark]
Natural agricultural methods include methods like intercropping, crop rotation, mixed cropping, etc which encourage the growth of different plants on the same piece of land. [1 Mark]
This not only replenishes the soil but also improves the biodiversity of that area. Growing the same crop over a long time rips the soil off its nutrients. Hence natural methods also help in improving biodiversity. [1 Mark]
