This set of Agricultural Biotechnology Multiple Choice Questions & Answers (MCQs) focuses on “Agriculture – New Approaches to Crop Production”.
1. The crop production can be increased by altering the basic generic structure of plants.
a) True
b) False
View Answer
Explanation: This is one of the simplest and direct ways to increase crop production. New characteristics are obtained by altering the genetic structure. This improves the efficiency of crop production.
2. Insects are benefactors.
a) True
b) False
View Answer
Explanation: In a natural ecosystem, organisms typically serve many functions. Insects, can be pests destroying crops and stored products. They can help in pollination and recycling organic waste.
