Biomes are both climatically and geographically defined. Biomes are regions of Earth that have similar climates and other abiotic (non-living) factors such as elevation, humidity, and soil type. No matter where they occur on the planet, biomes have similar types of vegetation and animal life, or ecological communities. In this lab, you will study the major types of terrestrial (land) biomes around the world and present one biome type to your classmates. You will also become familiar with a simple way to organize biomes by precipitation and temperature.
