| 5757160213 | Ammonification | The process by which fungal and bacterial decomposers break down the organic nitrogen found in dead bodies and waste products and convert it into inorganic ammonium (NH4+). | 1 | |
| 5757160214 | Anemia | A deficiency of iron. | 2 | |
| 5757160215 | Assimilation | The process by which producers incorporate elements into their tissues. | 3 | |
| 5757160216 | Biogeochemical Cycles | The movements of matter within and between ecosystems. | 4 | |
| 5757160217 | Denitrification | The conversion of nitrate (NO3-) in a series of steps into the gases nitrous oxide (N2O) and, eventually, nitrogen gas (N2), which is emitted into the atmosphere. | 5 | |
| 5757160218 | Evapotranspiration | The combined amount of evaporation and transpiration. | 6 | |
| 5757160219 | Famine | The condition in which food insecurity is so extreme that large numbers of deaths occur in a given area over a relatively short period. | 7 | |
| 5757160220 | Food insecurity | A condition in which people do not have adequate access to food. | 8 | |
| 5757160221 | Food security | A condition in which people have access to sufficient, safe, and nutritious food that meets their dietary needs for an active and healthy life. | 9 | |
| 5757160222 | Hydrologic Cycle | The movement of water through the biosphere. | 10 | |

| 5757160224 | Leaching | The transportation of dissolved molecules through the soil via groundwater. | 12 | |
| 5757160225 | Limiting Nutrient | A nutrient required for the growth of an organism but available in a lower quantity than other nutrients. | 13 | |
| 5757160226 | Macronutrients | The six key elements that organisms need in relatively large amounts: nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. | 14 | |
| 5757160227 | Malnutrition | Having a diet that lacks the correct balance of proteins, carbohydrates, vitamins, and minerals. | 15 | |
| 5757160228 | Mineralization | The process by which fungal and bacterial decomposers break down the organic matter found in dead bodies and waste products and convert it into inorganic compounds. | 16 | |
| 5757160229 | Nitrification | The conversion of ammonia (NH4+) into nitrite (NO2-) and then into nitrate (NO3-). | 17 | |
| 5757160230 | Nitrogen Fixation | A process by which some organisms can convert nitrogen gas molecules directly into ammonia. | 18 | |
| 5757160231 | Overnutrition | Ingestion of too many calories and improper foods. | 19 | |
