1. Biomes
Biome: an area that can be identified by its dominant plant (flora) and animal species (fauna) and prevailing climate

2. Climate: the temperature range, annual average precipitation, humidity, sunshine and wind in a region

3. Climax community: Plant and animal species that represent a stable state in a biome—after succession

4. Is it the biotic or abiotic factors that influence biomes?
