Terrestrial Biomes + Succession

The closer a biome is to the equator, the more we would expect it to be

• warmer & wetter
• warmer & drier
• cooler & wetter
• cooler & drier

The farther a biome is from the equator, the more we would expect it to be 

• warmer & wetter
• warmer & drier
• cooler & wetter
• cooler & drier

The tundra biome & the desert biome are both very dry, but

• the desert is always hot
• the desert has a wider temperature range
• the tundra has a wider temperature range
• they are also similar in temperature

Abiotic factors: hot and wet year-round; thin, nutrient-poor soils • Dominant plants: broad-leaved evergreen trees; ferns; large woody vines and climbing plants;  orchids and bromeliads

• Taiga 
• Temperate Rain Forest
• Temperate Deciduous Forest
• Tropical Rain forest

Abiotic factors: low precipitation, variable temperatures; soils rich in minerals but poor in organic material • Dominant plants: cacti and other succulents; creosote bush and other plants with short growth cycles

• Desert
• Tundra
• Tropical grassland
• Temperate grassland

Earth’s biomes are divided into _________ biomes, and __________biomes

• terrestrial, aquatic
• hot, cold
• north, south
• east, west

The most important abiotic factors when studying biomes are...

• Food and Water
• Water and Sunlight
• Temperature and Oxygen
• Precipitation and Temperature
