2. An organism that thrives in conditions with a high salt concentration.
4. A measure of the reflectivity of a surface
6. The industrial process that combines nitrogen from air with hydrogen from natural gas to produce ammonia.
10. Embankments that absorb and deflect noise, especially around mines, airports and major roads.
11. One of the first species to colonise an area at the start of ecological succession.
13. Winds that blow around the north and south poles in a circular manner which reduce the mixing of polar air masses with the rest of the atmosphere.
14. A large geographical region with particular climatic features, in which a characteristic, unique community of species lives eg Taiga, coral reefs, temperate grasslands, tundra, tropical rainforest

1. The release of animals from captivity where they are provided with post-release support such as food.
3. The 3D shape of the land surface.
5. The process of creating habitats that are similar to the conditions present before the natural habitat was changed by human actions.
7. A habitat that links other habitats so that animals can move between them.
8. A wetland area with an accumulation of dead plant material, especially moss.
9. Geological processes that change the form of a rock with heat and/or pressure, but without melting it.
12. The process of regularly cutting down tree branches above ground level, usually to prevent the regrowth being eaten by animals such as livestock or deer.
