Fertilizing crops
Irrigation
Pest control
None of the above
Domestic animals are allowed to overgraze the land
Too many crops are grown on the land and the land gradually loses its fertility
As a result of erosion, there is no fertile soil left to grow plants
All of the above
Organic land
Arable land
Vegetative land
All of the above
Using compost as fertilizer
Allowing land to lie fallow
Driving farm machinery over fields
All of these practices contribute to soil erosion
Beef cattle
Wheat
Dairy cows

Seeds are planted among the roots of the previous crop
More erosion is likely
Only organic fertilizers are used
All of the above
Genetic engineering
Subsistence farming
Aquaculture
Integrated pest management
Use ocean water instead of groundwater to irrigate crops
Increase the use of synthetic pesticides
Using rainwater instead of groundwater on crops
Adopt no-till farming methods
Does not breakdown quickly into harmless chemicals
Concentrates in the bodies of animals high in the food chain
Causes some birds to lay eggs so thin that they break when the birds sit on them
All of the above
Vitamins are of limited importance in growth and development
Humans need to get eight essential amino acids from the proteins they eat
Carbohydrates are mainly used to make membranes and hormones
Both (a) and (b)
The failure of food production to keep pace with population growth
Distribution problems caused by potential turmoil
New, higher-yield crops
Crop failure brought on by sustained drought
There were too few subsistence farmers
Use of pesticides and fertilizers increased the risk of population
Substantial resources were no longer required to grow the new grain varieties
All of the above
Remnants of the previous crop are left to slowly decay
Deep ridges are cut across, not down, the slopes of hills
The ground is carefully turned to mix soil nutrients
Only organic fertilizers and natural pesticides are used
