Food security | When all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life. |
Food web | A conceptual diagram that represents the feeding relationships of organisms within an ecosystem. It consists of a series of interconnected food chains. |

Fracture | Crack or linear break in a rock formation. |
Framework | Basic conceptual structure used to solve or address complex issues. |
Freshwater | Naturally occurring water on the Earth's surface in bogs, ponds, lakes, rivers and streams, and groundwater in aquifers and underground streams. Freshwater is characterized by having low concentrations of dissolved salts and other total dissolved solids. The term specifically excludes seawater and brackish water. |
