management with suitable examples.
Answers
Answer:
In Biotechnology, those products are created or manufactured beneficial to humans.
It is used in many industries including agriculture industry and drives innovation in the agricultural management.
For example, scientists use this technology as an equipment to develop pest-resistant crops, and produce enzymes to boost animals’ feed efficiency.
What is the impact of biotechnology on agriculture and other related fields?
Ans. (1) Natural characters of some species may not have all useful features. Some of the characters may be deleterious. In order to avoid such varieties, GMO or Genetically Modified Organisms are created. For this purpose, the DNA is changed in the crops. The modified crops then possess required features. (2) Following changes have occurred in the crops due to biotechnology. The varieties that can withstand the changes in the environment can be created. E.g., constantly changing temperature, dry and wet droughts, climate change and some similar stressor-resistant varieties are produced through genetic engineering. (3) GM crops are resistant to insect pests, pathogens, chemical weedicides, etc., due to their changed genome. This reduces the use and the cost of chemical pesticides which are harmful. (4) Due to use of seeds of GM crops, there is improvement in nutritive value of crops. Therefore now, seeds of a better quality crops are being produced. (5) There is also a decrease in loss of crops. Subsequently there is increase in the cultivable land and agriculture. (6) Some insect resistant crops such as Bt Cotton have Maharashtra. been produced which is widely used in
