The question was posed to me during an interview.

Asked question is from Microbes as Biocontrol Agents in chapter Microbes in Human Welfare of Biology – Class 12

Answer 1

Right option is (b) Use of biocontrol measures will increase our dependence on chemical fertilizers

Explanation: In biological farming, farmers understand the webs of interaction between the myriad of organisms that constitute the field flora and fauna. They also become familiar with the life cycles, feeding habits, pests and predators of various life forms that inhabit the field. Thus, the use of biocontrol measures greatly reduces our dependence on chemical fertilizers.
