| 4890102807 | Malnutrition | a person's diet lacks the correct balance of proteins, carbohydrates, vitamins, and minerals even though they get enough calories | 1 | |
| 4890102808 | Reasons for Under/malnutrition | Poverty Political and economic factors Agricultural resources being diverted to feed livestock and poultry rather than people | 2 | |
| 4890102809 | Overnutrition | too many calories and improper foods that causes a person to become overweight | 3 | |
| 4890102810 | Agribusiness | techniques of Industrial Revolution are applied to production of food | 4 | |
| 4890102811 | Green revolution | new management techniques and mechanization as well as the triad of fertilization, irrigation, and improved crop varieties | 5 | |
| 4890102812 | Waterlogging | when the soil remains under water for prolonged periods which impairs root growth because the roots cannot get oxygen |  | 6 |
| 4890102813 | Salinization | when the small amounts of salts in irrigation water become highly concentrated on the soil surface through evaporation | 7 | |
| 4890102814 | Organic fertilizers | organic matter from plants and animals, typically made from animal manure that has been allowed to decompose | 8 | |
| 4890102815 | Inorganic fertilizers (synthetic) | fertilizers that are produced commercially; this is usually done by combusting natural gas, which allows nitrogen from the atmosphere to be "fixed" and captured in fertilizer | 9 | |
| 4890102816 | Monocropping (monoculture) | growing a large amount of a single species of plant |  | 10 |
| 4890102817 | Pesticide | a substance that kills or controls organisms that people consider pests | 11 | |
| 4890102818 | Insecticide | targets insects | 12 | |
| 4890102819 | Herbicide | targets plants | 13 | |
| 4890102820 | Broad spectrum pesticides | designed to kill many different types of pests | 14 | |
| 4890102821 | Selective pesticides | designed to kill a narrower range of organisms | 15 | |
| 4890102822 | Persistent | pesticides that remain in the environment a long time | 16 | |
| 4890102823 | Nonpersistent | pesticide that breaks down relatively rapidly, usually in weeks to months | 17 | |
| 4890102824 | Bioaccumulation | some pesticides are found to build-up over time in the fatty tissues of predators | 18 | |
| 4890102825 | Resistance | pest populations may evolve resistance to a pesticide over time | 19 | |
| 4890102826 | Pesticide treadmill | the cycle of pesticide development followed by pest resistance, followed by development of a new pesticide |  | 20 |
| 4890102827 | Benefits of Genetic Engineering | Greater yield Greater food quality Reductions in pesticide use Reduction of world hunger by increased food production Increased profits | 21 | |
| 4890102828 | Concerns about GMO's | Safety for human consumption Effects on biodiversity Regulation of genetically modified organisms | 22 | |
| 4890102829 | Conventional agriculture | industrial agriculture where labor is reduced and machinery is used | 23 | |
| 4890102830 | Traditional farming | still used in the developing world where human labor is used and not machinery | 24 | |
| 4890102831 | Shifting agriculture | used in areas with nutrient-poor soils; involves planting an area for a few years until the land is depleted of nutrients and then moving to another area and repeating the process | 25 | |
| 4890102832 | Nomadic grazing | moving herds of animals to find productive feeding grounds | 26 | |
| 4890102833 | Desertification | soil is degraded by agriculture to the point at which they are not longer productive | 27 | |
| 4890102834 | Sustainable agriculture | producing enough food to feed the world's population without destroying the land, polluting the environment, or reducing biodiversity; next four are examples |  | 28 |
| 4890102835 | Intercropping | two or more crop species are planted in the same field at the same time | 29 | |
| 4890102836 | Crop rotation | rotating crops species from season to season | 30 | |
| 4890102837 | Agroforestry | intercropping trees with vegetables | 31 | |
| 4890102838 | Contour plowing | plowing and harvesting parallel to the land to prevent erosion | 32 | |
| 4890102839 | No till agriculture | helps to stop soil degradation by leaving crop residues in the fields and not tilling the land after each harvest | 33 | |
| 4890102840 | Integrated pest management | using a variety of techniques designed to minimize pesticide inputs; crop rotation, intercropping, planting pest resistant crop varieties, creating habitats for predators, and limited use of pesticides | 34 | |
| 4890102841 | Organic agriculture | production of crops without the use of synthetic pesticides or fertilizers | 35 | |
| 4890102842 | CAFO (concentrated animal feeding operations) | large structures where animals are being raised in high density numbers |  | 36 |
| 4890102843 | Fishery | a commercially harvestable population of fish within a particular ecological region | 37 | |
