High responder crops of the green revolution produce tremendous yields: a. even in severe drought conditions. c. in response to fertilizers, pesticides, and irrigation. d. in all conditions where standard crops fail. e. in response to fertilizers, pesticides, and irrigation and only “good” yields in less than ideal situations. Green Revolution: The technological transfer, new methods of agriculture and scientific research in the period of 1960 brought a revolution in agriculture by increasing the production of food. This transformation is called the green revolution. Norman Borlaug was an agricultural scientist who won Noble for his contribution to the green revolution.
Define the terms “green revolution” and “gene revolution.” What is the difference between them? Biotechnology: Biotechnology is widely used in the agricultural sector, vaccine development, IVF (In-vitro fertilization), medicine, genetic engineering, and many more fields. It has increased the efficiency of tissue culture and micropropagation techniques. Biotechnological tools help to enable genetic modifications in plants and animals.
One of the problems associated with the “green revolution” is that:
A. not enough food is produced for developing countries.
B. it is confined to highly developed countries.
C. it makes developing countries dependent on high-energy-consuming imported technologies.
D. technology is not advanced enough to make it cost-effective.
Answer to question 1
The correct option is e. in response to fertilizers, pesticides, and irrigation, and only “good” yields in less than ideal situations.
The production of crops has increased in the green revolution by following modern agricultural methods, which involved fertilizers, pesticides, and different irrigation methods. The high yielding genetically modified crops produced a good yield in less than the ideal situation for traditional crops.
a. even in severe drought conditions — This option is incorrect because the agricultural method used in the green revolution included irrigation, and the crops were high yielding rather than drought adaptive.
c. in response to fertilizers, pesticides, and irrigation — This option is incorrect because option e is more suitable.
d. in all conditions where standard crops fail — This option is incorrect because fertilizers, pesticides, and irrigation are key elements of the green revolution.
Answer to question 2
Green revolution was implemented to boost the farming sector and to increase the production of wheat and rice. The main purpose of the green revolution was to increase the amount and quality of crops.
Gene revolution was implemented to use tools & techniques of biotechnology in the agricultural sector. The main purpose of the gene revolution was to create hybrid seeds and pesticide-resistant products.
The difference between green and gene revolution is:Green revolution uses traditional techniques like tissue culture and breeding methods to make some changes at the genetic level in wheat and rice plants. Gene revolution uses the latest biotechnological tools like gene guns and recombinant DNA technology to make some changes at the molecular level in seeds.
Answer to question 3
The green revolution leads to an increase in the production of grains which was a very good change in agriculture in terms of production but it was only done by using higher inputs like costly fertilizers and crop varieties and other inputs. It increased the cost of production in developing countries that cannot be afforded by small and marginal farmers. Also, high-energy consuming technologies were needed to increasing the yield.
Therefore, the correct answer is _ C. it makes developing countries dependent on high-energy-consuming imported technologies.
Please note that:
Option A is incorrect because the green revolution produced enough food for developing countries even the export of grain was increased.
Option B is incorrect because the green revolution mainly affected developing countries.
Option D is incorrect because in the green revolution advanced technologies were used that were cost-effective.
