Exploring Earth's Diverse Biomes

What primarily determines the types of plant species in a given area?

• Soil type

• Annual patterns of temperature and rainfall

• Ocean proximity

• Altitude

Which adaptation is specifically associated with desert biomes?

• Grasses

• Coniferous trees

• Cacti

• Broadleaf trees

What is the main difference between a biome and a climate zone?

• There is no significant difference.

• Biomes are larger than climate zones.

• Climate zones are defined by plant life, while biomes are not.

• Biomes include adaptations of plants, influenced by climate and other factors.

Which factor does NOT influence the distribution of plant species across different regions?

• Local climate patterns

• Presence of animals

• Evolutionary history

• Soil drainage

What role does soil type play in the distribution of plant species?

• It has no significant impact.

• It influences water drainage and affects which species can thrive.

• It determines the biome classification.

• It solely determines the local climate.

What is the significance of Vladimir Koppen in climate classification?

• He classified the thirteen biomes.

• His work has dominated climate classification for over a century.

• He developed the aridity index.

• He discovered the concept of evapotranspiration.

What does the aridity index represent?

• The ratio of annual rainfall to temperature

• The maximum potential water loss through evapotranspiration

• The total annual precipitation

• The ratio of potential evapotranspiration to total rainfall

Why do boreal forests have extensive biomass despite similar annual rainfall to the semi-arid Sahel?

• More efficient water retention due to cooler temperatures in boreal forests

• Different soil types

• Higher temperatures in the Sahel

• Presence of permafrost in boreal forests

Which biome is characterized by broadleaf trees that retain their leaves year-round?

• Savannah

• Temperate Forest

• Boreal Evergreen Forest

• Tropical Evergreen Forest

Which biome is characterized by the dominance of grasses due to lack of rain and cooler temperatures?

• Savannah

• Prairie and Steppe

• Tropical Evergreen Forest

• Shrubland
