Question 1

What is required by industrialized agriculture?
A)large amounts of pesticides
B)small amounts of water
C)small amounts of fossil fuels
D)no inorganic fertilizers

Question 5

Which type of agriculture is most characteristic of developing countries?
A)plantation agriculture
B)traditional subsistence agriculture
C)traditional intensive agriculture
D)industrialized agriculture

Accepted Answer

Traditional subsistence agriculture is most characteristic of developing countries, as it involves small-scale farming for the purpose of feeding the family or local community. This type of agriculture is labor-intensive and relies on traditional methods and tools, with little use of technology or outside inputs. Plantation agriculture and industrialized agriculture are typically found in more developed countries, while traditional intensive agriculture may be used in developing countries but is not as common as subsistence farming.

Question 6

Which crops were specially bred for tropical and subtropical climates, and were the outcome of genetic research conducted during the green revolution?
A)dwarf varieties of corn and potatoes
B)dwarf varieties of sugarcane and pineapples
C)dwarf varieties of rice and wheat
D)dwarf varieties of bananas and coconuts

Accepted Answer

Dwarf varieties of rice and wheat were bred for tropical and subtropical climates as part of the green revolution. These varieties had shorter stalks, allowing them to resist wind damage and support the weight of larger grain heads. This increased yield and made them more resistant to pests and diseases.

Question 7

What does intercropping involve?
A)It involves growing several different crops on a plot of land.
B)It involves growing several varieties of one crop on a plot of land.
C)It involves growing trees and crops together on a plot of land.
D)It involves growing crops in alternate rows on a plot of land.

Accepted Answer

Intercropping involves growing several different crops on a plot of land. This is done to enhance overall productivity by making use of resources more efficiently, reducing pest and disease damage, and increasing soil fertility. Therefore, option A is the correct answer.

Question 8

Which law represents the fact that the initial dramatic yields realized by crops that have received inputs of energy, water, fertilizer, and pesticides eventually level off?
A)the first law of thermodynamics
B)the tragedy of the commons law
C)the prevention vs.treatment law
D)the law of diminishing returns

Accepted Answer

The law of diminishing returns states that as more and more inputs are added to a crop or production process, the marginal increase in output will eventually decrease to the point of diminishing returns. Therefore, the initial dramatic yields realized by crops that have received inputs of energy, water, fertilizer, and pesticides eventually level off due to this law.

Question 9

Which food is among the three foods that make up half of the calories consumed by humans?
A)fish
B)wheat
C)beef
D)soybean

Accepted Answer

Wheat is one of the three staple foods that make up half of the calories consumed by humans, alongside rice and maize.

Question 10

What percentage of Canada's GNP does agriculture contribute?
A)9%
B)18%
C)28%
D)38%

Accepted Answer

According to Statistics Canada, agriculture contributes approximately 9% to Canada's Gross Domestic Product (GDP).

Question 11

What is the main reason for the increase in global food production since 1950?
A)the blue revolution
B)the red revolution
C)the yellow revolution
D)the green revolution

Accepted Answer

The green revolution, characterized by the introduction of high-yielding crop varieties, increased use of fertilizers and pesticides, and improved irrigation systems, led to significant increases in global food production since 1950.

Question 12

What is a garden plot called in which corn is planted next to nitrogen-restoring alfalfa?
A)It is agroforestry.
B)It is intercropping.
C)It is a polyculture.
D)It is polyvarietal cultivation.

Accepted Answer

Intercropping refers to planting two or more crops in close proximity to each other, usually for mutual benefit. In this case, planting corn and alfalfa together can be beneficial because as the corn uses up soil nitrogen, the alfalfa can fix nitrogen from the air and replenish it in the soil. Agroforestry involves intentionally planting trees with crops or livestock for benefits such as shade or windbreaks, but does not necessarily involve corn and alfalfa. Polyculture refers to planting multiple crops together, but does not necessarily involve the specific combination of corn and alfalfa. Polyvarietal cultivation involves planting multiple varieties of a single crop.

Question 13

Which type of agriculture usuallyinvolves growing only a single type of crop?
A)plantation agriculture
B)industrialized agriculture
C)minimum-tillage agriculture
D)traditional intensive agriculture

Accepted Answer

The answer of Which type of agriculture usuallyinvolves growing only...

Question 14

Which term bestapplies to a farm where alternating rows of hemp and maple trees have been planted?
A)It is intercropping.
B)It is a monoculture.
C)It is agroforestry.
D)It is polyvarietal cultivation.

Accepted Answer

Agroforestry is the combination of agriculture and forestry practices in which crops or trees are intermixed or planted in proximity to each other to provide benefits such as improved soil quality, pest control, and biodiversity. In this scenario, the alternating rows of hemp and maple trees indicate agroforestry.

Question 15

Which of the following is a type of subsistence agriculture?
A)shifting cultivation of small plots in tropical forests
B)coffee plantations
C)large cornfields
D)intensive cultivation plots

Accepted Answer

Shifting cultivation of small plots in tropical forests is a type of subsistence agriculture where farmers clear a small area of forest to grow crops for a few years and then move on to another area once the soil loses its fertility. It is mainly practiced in areas with poor soil quality and limited resources. B, C, and D are not types of subsistence agriculture. Coffee plantations and large cornfields are commercial agriculture practices, while intensive cultivation plots are typically associated with small-scale commercial farming.

Question 16

How many domesticated animal species provide the majority of the meat and animal products consumed by humans?
A)about 32
B)about 24
C)about 16
D)about 8

Accepted Answer

The majority of the meat and animal products consumed by humans come from approximately 8 domesticated animal species. These include cattle, pigs, chickens, sheep, goats, rabbits, ducks, and geese, which are the primary sources of animal protein in human diets globally.

Question 17

Which type of agriculture is mostcharacteristic of developed countries?
A)traditional subsistence agriculture
B)traditional intensive agriculture
C)plantation agriculture
D)industrialized agriculture

Accepted Answer

Developed countries typically use industrialized agriculture, which involves the use of technology, large-scale monoculture farming, and chemical inputs to increase yields and efficiency. This type of agriculture allows for the production of large quantities of food with fewer labor inputs, and is designed to maximize profits for farmers and agribusinesses. Traditional subsistence and intensive agriculture are more commonly found in developing countries, while plantation agriculture is primarily associated with tropical regions and the production of cash crops for export.

Question 18

Question 20

What characterizes the plants of the second green revolution?
A)They are adapted to drought.
B)They are giant varieties.
C)They are slow growing.
D)They are high-yield varieties.

Accepted Answer

The plants of the second green revolution are characterized as high-yield varieties. They have been developed to improve crop productivity and increase yield. They are often genetically modified and have traits that make them resistant to pests, diseases, or environmental stress. Adaptation to drought (A) and giant size (B) are not necessarily characteristics of the second green revolution. Slow growth (C) would not be desirable since it would mean a longer time to harvest and less productivity.
