| biofouling | biologische Verschmutzung | |
| biofuel | biogener Brennstoff | |
| biofuel (A gaseous, liquid, or solid fuel that contains an energy content derived from a biological source. The organic matter that makes up living organisms provides a potential source of trapped energy that is beginning to be exploited to supply the ever-increasing energy demand around the world. An example of a biofuel is rapeseed oil, which can be used in place of diesel fuel in modified engines. The methyl ester of this oil, rapeseed methyl ester (RME), can be used in unmodified diesel engines and is sometimes known as biodiesel. Other biofuels include biogas and gasohol) | Biokraftstoff | |
| biogas (Gas, rich in methane, which is produced by the fermentation of animal dung, human sewage or crop residues in an air-tight container. It is used as a fuel, to heat stoves, lamps, run small machines and to generate electricity. The residues of biogas production are used as a low-grade organic fertilizer. Biogas fuels do not usually cause any pollution to the atmosphere, and because they come from renewable energy resources they have great potential for future use) | Biogas | |
| Biogas process | Biogasverfahren | |
| Biogas process | Faulgasverfahren | |
| biogenetic reserve | biogenetisches Schutzgebiet | |
| biogenic and anthropogenic emissions | biogene und anthropogene Emissionen | |
| Biogenic Emissions in the Mediterranean Area | biogene Emissionen in Mittelmeerraum | |
| biogeocenose | Ökosystem | |
| biogeochemical cycle | biogeochemischer Zyklus | |
| biogeochemical cycle | Biogeochemischer Kreislauf | |
| biogeochemical cycle | biogeochemische Zyklen | |
| 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) | Biogeochemischer Kreislauf | |
| biogeochemistry | Biogeochemie | |
| biogeocoenosis | Ökosystem | |
| biogeographical region (Area of the Earth's surface defined by the species of fauna and flora it contains) | Biogeographische Regionen | |

| biogeography (The science concerned with the geographical distribution of animal and plant life) | Biogeographie |
