What is crop rotation?
Planting different types of crops in alternating patterns
The rotation of crops in a field from one period of time to the next
The transformation of slopes into different steps
Rows planted in a field to slow down the wind
What type of farming is this?
Intercropping
Contour Farming
Terracing
Crop Rotation
What type of farming is this?
Shelterbelts
No Till Farming
Crop Rotation
Intercropping
A build up of salts in surface soil layers is called
Irrigation
Salinization
Inorganic fertilizers
Overgrazing
What is irrigation?
Flooding plants to the point of suffocation
Synthetically manufactured mineral supplements
Excessive grazing of fields
Artificial provision of water to support agriculture
Which of the following is the most likely result from clearing mature, forested land and converting it into agricultural land that would be used for cattle grazing?
There will be a decrease in the amount of runoff into nearby streams.
There will be a reduction in the emission of greenhouse gases released into the atmosphere.
There will be an increase in the diversity and size of primary producers.
There will be a reduction in the uptake of atmospheric carbon dioxide.
Which of the following are the different particle sizes that determine soil texture?
loam, mud, sand
clay, sand, loam
silt, loam, clay
clay, silt, sand
When roots become saturated with water due to over-irrigation, it causes death in plant roots. This is called:
salinization
desertification
agroforestry
waterlogging
When irrigation water evaporates, salts are left behind on the soil surface and can cause plant death or lead to
soil salinization
desertification
waterlogging
monocropping
Because global fisheries have dramatically seen a reduction in fish numbers, this technique has been used recently to supplement that loss.
monocropping
IPM
contour farming
aquaculture
A method of cultivation in which forests are burned and cleared for planting
(a)
An organism whose DNA has been modified in the laboratory in order to favor the expression of desired physiological traits or the production of desired biological products.
(a)
A large increase in crop production in developing countries achieved by the use of fertilizers, pesticides, and high-yield crop varieties.
(a)
An economics problem in which every individual has an incentive to consume a resource, but at the expense of every other individual.
(a)
A method of irrigation where farmers flow water down small trenches running through their crops.
(a)
This method of irrigation is conducted by creating small parallel channels along the field length in the direction of predominant slope.
(a)
This is a method of applying water to a controlled manner in that is similar to rainfall. The water is distributed through a network that may consist of pumps, valves, pipes, and sprinklers.
(a)
A method of extracting minerals near the surface of the Earth
(a)
The process or industry of obtaining ore or coal by open-pit mining.
(a)
Cultivation in which different crops are sown in alternate strips to prevent soil erosion
(a)
What is the definition of the tragedy of the commons?
when humans overuse a natural resource
when the short-term, positive effects go to the individual, while the long-term, negative effects are spread out to the group
when humans act selfishly, thinking of the own interest
when plants and animals compete for space, resources, and/or food
Sustainability is
the process of maintaining resources so they are not depleted or permanently damaged
the ability to use resources faster than they are renewed
they ability to save resources for years and years
the process of using resources for one's own benefit without regard for others
What is meant by overgrazing?
When the cows eat too much and get sick
When a section of land is used for an extended period of time without sufficient recovery periods
When too much grass is planted
When a section of land is not used for an extended period of time and becomes overgrown
What is a negative consequence of overgrazing?
The land can turn into a desert (desertification) and can no longer be used for feeding or agriculture.
The cows become overweight.
Vegetation becomes overfertilized and grows uncontrollably.
Vegetation becomes plentiful and lasts for decades.
What is overfishing?
The removal of a bad fish from an environment?
The removal of a dead fish from a body of water.
The over-breeding of fish.
The removal of a fish species from a body of water at rate faster than the species can repopulate.
What is one negative consequence of overfishing?
Fish can grow two heads.
Fish species can either become depleted or very underpopulated in that given area.
Fish species can adapt in order to escape the fisherman.
Fish species will move to a new environment in order to escape fishermen.
Which of the following is NOT a benefit of aquaculture?
Reduces risk of fishery collapse
Requires small amount of water, space and fuel
Doesn't take up a vast amount of land space
Fish produce low concentration of waste
What type of irrigation practice acts as a solution for waterlogging and salinization?
Drip Irrigation
Furrow Irrigation
Flood Irrigation
Spray Irrigation
Which of the following is NOT a disadvantage of monocropping?
Greatly decreases biodiversity
Inefficient for harvest, pesticide and fertilizer application
Increases soil erosion
Decreases habitat diversity for species living in area
Which of the following is an example of a solution to the tragedy of the commons?
Improving literacy among urban populations
Raising tax rates for large corporations
Inventing stronger antibiotics
Passing a law to set limits for fishermen
