2 What is a Biome?A biome is a large region characterized by a specific type of climate and certain types of plants & animal communities.Described by their vegetation.Plants that grow in an area determine the other organisms that can live there.
4 Consider this hierarchy model: BIOSPHERE BIOMES SMALLER ECOSYSTEMS
5 What factors determine which plants can grow in a certain area? Remember that biomes are defined by their plant lifeClimateRefers to the weather conditions, such as temperature, precipitation, humidity, & winds, in an area over a long period of time.Temperature & PrecipitationDetermines a region’s climateAll organisms need water, and the larger an organism is, the more water it needs.
7 Latitude & VegetationBiomes, climate, and vegetation vary with latitude & altitude.Latitude is the distance north or south of the equator and is measured in degrees.Altitude is the height of an object above sea level.

12 ReviewWhy is it hard for trees to survive at the tops of very high mountains?Which biome would you expect to find a warm to hot conditions with a large amount of moisture?Coniferous trees can be found in both the subartic taiga and in warm chaparral regions. What kind of conditons have these trees in these areas adapted to?
