BIOMES REVIEW

Extreme temperatures, abundant precipitation, rich, deep soils, and a growing season of four to six months represent a

• a tropical rain forest
• a taiga
• savanna

The biome with the highest species diversity is the

• taiga
• tundra
• tropical rain forest

Hot summers and cold winters, low to moderate rainfall, few trees, and rich, fertile soil represent a

• temperate deciduous forest
• grasslands
• taiga

As you move from the equator toward the North Pole, you would be likely to see

• grasslands, then tundra, then rain forests
• rain forests, then deserts, then taiga

Factors that influence where plants grow include

• climate 
• longitude
• biome maps

Thin soil, high humidity, and high rainfall represent a

• tropical rain forest.
• temperate rain forest.
• desert
• grasslands

The top layer in a tropical rain forest is the

• understory
• canopy
• forest floor
