2024 QUESTIONS AND CORRECT DETAILED
ANSWERS WITH RATIONALES (VERIFIED
ANSWERS) |ALREADY GRADED A+
What are the major causes of food insecurity? - Answer -poverty, political upheaval,
corruption, war, imbalance between food production and consumption in affluent
societies and impoverished societies, and environmental degradation
What are the three major food systems? - Answer -croplands, rangelands, ocean
fisheries
croplands - Answer -produce mostly grain, but also vegetables and fruit; provide almost
77% of the world's food using 11% of the land area
rangelands - Answer -used to raise animals for meat; meat provides 16% of the world's
food and uses 29% of the land area
ocean fisheries - Answer -provide approximately 7% of the global food supply; obtaining
our fish supply affects over 95% of the world's oceans
monoculture - Answer -producing one single crop over a wide area
polyculture - Answer -producing multiple crops in a limited space to mimic natural
biodiversity in an area
industrialized or high-input agriculture - Answer -genetically modified plants harvested
by using heavy equipment, fertilizers, pesticides and lots of water
plantation agriculture - Answer -cash crops planted and harvested here to meet
worldwide needs; grown on a large scale and monocultures are dominant; tropical
forests are often cleared to make way for large warehouses or fields where these cash
crops can be grown under controlled conditions; fertilizers are used to control pest
species and an abundance of water and energy is needed to grow these crops
traditional intensive agriculture - Answer -uses mostly the labor of animals and their
owners to produce enough to survive; polyculture; not high yields here, but as demand
increases, some traditional farmers are turning to fertilizers and other chemical agents
to boost their yields
Is monoculture considered industrialized agriculture, subsistence agriculture, or both? -
Answer -industrialized agriculture; growing only one crop increases yields
, Are cash crops considered industrialized agriculture, subsistence agriculture, or both? -
Answer -industrialized agriculture; grown in tropical areas (coffee, bananas)
Is hope to increase yield considered industrialized agriculture, subsistence agriculture,
or both? - Answer -all farmers want a high yield each year
Are animal labor, fertilizer and water use considered industrialized agriculture,
subsistence agriculture, or both? - Answer -subsistence agriculture
Is polyculture considered industrialized agriculture, subsistence agriculture, or both? -
Answer -subsistence agriculture; many crops are grown on one field, biodiverse
Is fossil fuel consumption considered industrialized agriculture, subsistence agriculture,
or both? - Answer -industrialized agriculture; high input agriculture needs lots of energy
subsistence agriculture - Answer -self-sufficiency farming in which the farmers focus on
growing enough food to feed themselves and their families
What were the three steps that led to the increase in productivity from the Green
Revolution? - Answer -key crops were genetically engineered to produce high yields
and were planted in monoculture plots; pesticides, fertilizers, and water were used to
maximize crop yield; same crops were grown at max amount yo increase yield of
particular crop
Green revolution - Answer -movement to use key crops such as wheat, rice, and corn to
produce large amount of food; plants are often genetically modified to produce high
yields; farmers are encouraged to grow only one species at a time; large quantities of
fertilizers and pesticides are used on crops to increase yield
R horizon - Answer -solid bedrock that starts formation of soil; unaltered parent material
How is soil formed? - Answer -weathering breaks the solid rock into smaller pieces,
covering the R horizon with C horizon; rock breaks up and creates spaces for biotic
materials, as animals and plants invade area they create A horizon (topsoil); A horizon
gets deeper over time, O horizon may form over A horizon; over time water moves
through soil carrying minerals and clay particles from A horizon into B horizon
A horizon - Answer -more weathered than the C horizon, is made of finer-grained
materials, and contains more organic matter than the C horizon; thin A horizon over a C
horizon is usually a sign of a relatively young soil
C horizon - Answer -weathered, or decomposed, rock; young soil is just C horizon
O horizon - Answer -layer of organic-rich soil that forms from the decay of large plants
and animals; leaf litter layer at the forest floor, or the dark crumbly layer at the surface of
