This set of Basic Biotechnology Multiple Choice Questions & Answers (MCQs) focuses on “Biomass Strategy”.
1. The annual net yield of plant biomass, from photosynthesis, on land in terms of dry matter is _____
a) 120 billion tons
b) 500 billion tons
c) 2 billion tons
d) 4 billion tons
View Answer
Explanation: Annual net yield of plant biomass from photosynthesis is 120 billion tons of dry matter on land. Land produced biomass is mostly lignocellulosic. Dry matter is lesser in oceans though.
2. The annual net yield of plant biomass, from photosynthesis, on ocean in terms of dry matter is _____
a) 200 billion tons
b) 50 billion tons
c) 300 billion tons
d) 400 billion tons
View Answer
Explanation: Annual net yield of plant biomass from photosynthesis is 50 billion tons of dry matter on ocean. Ocean produced biomass is also mostly lignocellulosic. Dry matter is more in lands though.
3. The highest proportion of land-based biomass is produced as ____________
a) zoo
b) forest
c) garden
d) park
View Answer
Explanation: The highest proportion of land-based biomass is produced as forest. Land-based biomass is about 44%. Forest biomass is followed by grasslands.
4. Agricultural crops account for how much percent of primary photosynthetic productivity?
a) 6%
b) 99%
c) 98%
d) 97%
View Answer
Explanation: Agricultural crops account for only 6% of primary photosynthetic productivity. From this a major proportion of food for humans and animals is derived. Structural materials, textiles and papers are also derived from this.
5. Traditional agricultural products may be well exploited with increasing awareness of biotechnology.
a) True
b) False
View Answer
Explanation: Traditional agricultural products are good enough pest resistant. These are also high yielding in nature. Traditional agricultural products may be well exploited with the increasing awareness of biotechnology.
6. New technological approaches will undoubtedly be able to utilize waste materials from food processing.
a) True
b) False
View Answer
Explanation: Large volume of waste materials is produced from food processing industries. New technological approaches can utilize them well. The principle of 3R is well observed.
7. Biotechniques hold great economic potential in ______________
a) tropical and subtropical regions
b) evergreen forests
c) deciduous forests
d) grassland
View Answer
Explanation: Biomass agriculture, aquaculture and forestry are biotechniques. They hold great economic potential for national economies. The economies are generally of tropical and subtropical regions.
8. The development of biotechnological process in developing areas, where plant growth excels, can bring a change in the balance of ____________
a) economic power
b) climate
c) temperature
d) robotics
View Answer
Explanation: Development of biotechnological processes is necessary. In developing areas with good plant growth, the economic power varies. It can bring a change in the balance of economic power.
9. What can be derived from ancient biomass?
a) Software
b) Robot
c) Sunlight
d) Petrochemical feedstocks
View Answer
Explanation: Petrochemicals are non-renewable feedstocks. Modern society is dependent on non-renewable feedstocks very much. It is now proved that these can be derived from ancient feedstocks.
10. What do modern industrialized nation depend upon for energy for production processes?
a) Fossil reserves
b) Software
c) Technology
d) Music
View Answer
Explanation: Modern industrialized nations rely on fossil reserves for energy. They also rely upon it for production processes. The industrial world is highly dependent on fossils.
11. World’s known available sources of oil and gas will have been fully exploited by what time?
a) End of his century
b) In text million years
c) In next billion years
d) In next zillion years
View Answer
Explanation: Coal stocks may last for many hundred years. But it is not true for oil and gas. It is predicted to extinguish by the end of this century.
12. Mentioned below are the products derived from biomass. Based on your understanding, predict what is ‘X’?
a) Fertilizers
b) Freezers
c) Fish
d) Egg
View Answer
Explanation: Fuels include biogas, pyrolysis products, oils and alcohols. Feedstocks include synthetic gases and feeds are supplements. The only remaining substance is fertilizer which includes compost and sludge.
