Dear candidate there is no B.Sc Biology course, either you have to do B.Sc in Botany or B.Sc in zoology, or there is particular course for B.Sc Agriculture. But if you do B.Sc Botany Course then also you can an agriculture officer. If you pass your Bachelor's degree with a good percentage, then followed by completing your higher studies you can opt for the role of Agriculture Officer.

All the best for future

Good luck!!
