| alimentary cycle | ciclo alimentario |
| audit cycle | ciclo de auditoría ambiental |
| audit cycle | ciclo de auditoría |
| biogeochemical cycle | ciclos biogeoquímicos |
| biogeochemical cycle Movement of chemical elements in a circular pathway, from organisms to physical environment, back to organisms. The process is termed a nutrient cycle if the elements concerned are trace elements, which are essential to life. A biogeochemical cycle occurs when vegetation decomposes and minerals are incorporated naturally in the humus for future plant growth | ciclos biogeoquímicos |
| biological cycle A series of transformations or biological events which follow one after the other one, reaching at the end of the cycle the initial conditions, as in the life cycle of many animal and plant organisms | ciclo biológico |
| carbon cycle | ciclo del carbono |
| carbon cycle | ciclo del carbón |
| carbon cycle The cycle of carbon in the biosphere, in which plants convert carbon dioxide to organic compounds that are consumed by plants and animals, and the carbon is returned to the biosphere in inorganic form by processes of respiration and decay | ciclo del carbón |

| combined cycle-power station | central eléctrica de ciclo combinado |
| combined cycle-power station This type of plant is flexible in response and can be built in the 100-600 MW capacity range. It produces electrical power from both a gas turbine (ca. 1300°C gas inlet temperature), fuelled by natural gas or oil plus a steam turbine supplied with the steam generated by the 500°C exhaust gases from the gas turbine. The thermal efficiency of these stations is ca. 50 per cent compared with a maximum of 40 per cent from steam turbine coal fired power stations. This type of plant can be built in two years compared with six years for a coal-fired station and 10-15 years for nuclear | central eléctrica de ciclo combinado |

| hydrologic cycle The movement of water between the oceans, ground surface and atmosphere by evaporation, precipitation and the activity of living organisms, as one of the mayor biogeochemical cycles. Each day water evaporates from the oceans and is carried in the air from the sea over the land, which receives it as precipitation, and finally returns from the land to the sea through rivers, thus completing the cycle | ciclo hidrológico |
