2
A
monoculture
crop:
is usuall organic
is a polyculture
is more susceptible to insect damage
requires less fertilizer
3
What is the greatest source of Greenhouse gases Cattle produce?
methane (CH4)
CO2
O2
CO
4
Broad-spectrum pesticides are dangerous because they:
only kill one pest
cause dead zones
kill all the beneficial insects as well
cause sediment pollution
5
A disadvantage of GMO's is that:
prevents crop diseases
increased crop yield
could decrease starvation in developing countries
could cause pest resistance
6

clay
sandy loam
silty clay loam
7
Groundwater (Aquifers) can be contaminated by which of the following?
greenhouse gases
GMOs
herbicides and pesticides
dead zones
8
In order to reduce soil salinization, farmers should implement which strategy(s):

aren't getting enough calories
are eating too many carbs
are eating the wrong type of food
17
"Dead Zones" are a result of synthetic fertilizers. Why does it cause the loss of aquatic life?
causes sediment pollution
Increases in pH
Clogs gills of fish
causes a rapid decrease in O2
18
As advantage of GMOs is that:
they can grow in nutrient poor soils
they can cause allergies
kill monarch larvae
they have unknown environmental impacts
19
Organic food has which of the following properties?
No GMOs
No synthetic pesticides
All the above
No Synthetic herbicides
20
Soil Salinization results from:
