Q: Fire-resistant plants are a common adaptation in which biome, and what is the primary ecological reason for this adaptation?

Mediterranean Woodland & Shrubland; frequent fire regimes shape plant evolution.

Q: A farmer is considering converting land in a biome with deep, fertile soils and moderate precipitation (300–1000 mm/year) to agriculture. What is a likely long-term consequence of this conversion?

Loss of organic matter and reduced soil fertility over time.

Q: Which biome is most likely to have soils classified as lithosols, and what does this classification indicate?

Desert; soils are extremely low in organic matter and mostly composed of stone.

Q: Which of the following adaptations would you expect to find in desert plants to minimize water loss?

Dense cover of plant hairs and small leaves.

Q: A climate diagram for a biome shows precipitation peaking in winter and spring, with hot, dry summers. Which biome does this most likely represent?

Mediterranean Woodland & Shrubland

Q: Which of the following best describes the role of mycorrhizae in tropical rain forest soils?

They help plants obtain nutrients from nutrient-poor, acidic soils.

Q: Which of the following is a major human impact on Mediterranean woodland and shrubland biomes?

Clearing for agriculture and urban development.

Q: Which of the following best describes the climate and vegetation of temperate grasslands?

Moderate precipitation, deep fertile soils, dominated by herbaceous plants.

Q: Which biome is most likely to have moderate soil fertility, evergreen trees and shrubs, and a long history of human intrusion?

Mediterranean Woodland & Shrubland

Question 1

Which of the following best explains why tropical rain forest soils are typically nutrient-poor despite high plant diversity?

Accepted Answer

Heavy rainfall leads to leaching and rapid decomposition, causing nutrients to be tied up in living tissues rather than in the soil.

Question 2

A scientist is studying a biome with the following characteristics: deep, fertile soils, periodic droughts, and dominated by herbaceous vegetation. Which biome is most likely being studied?

Accepted Answer

Temperate Grassland

Question 3

Which equation best represents the relationship between precipitation ($P$) and evaporation ($E$) in a desert biome?

Accepted Answer

$P < E$

Question 4

Fire-resistant plants are a common adaptation in which biome, and what is the primary ecological reason for this adaptation?

Accepted Answer

Mediterranean Woodland & Shrubland; frequent fire regimes shape plant evolution.

Question 5

A farmer is considering converting land in a biome with deep, fertile soils and moderate precipitation (300–1000 mm/year) to agriculture. What is a likely long-term consequence of this conversion?

Accepted Answer

Loss of organic matter and reduced soil fertility over time.

Question 6

Which biome is most likely to have soils classified as lithosols, and what does this classification indicate?

Accepted Answer

Desert; soils are extremely low in organic matter and mostly composed of stone.

Question 7

Which biome is characterized by evergreen conifers, low soil fertility, and slow decomposition rates due to low temperatures and low pH?

Accepted Answer

Boreal Forest

Question 8

If a region experiences little temperature variation throughout the year and annual rainfall of approximately 2000 mm, which biome is it most likely to be?

Accepted Answer

Tropical Rain Forest

Question 9

Which of the following adaptations would you expect to find in desert plants to minimize water loss?

Accepted Answer

Dense cover of plant hairs and small leaves.

Question 10

A climate diagram for a biome shows precipitation peaking in winter and spring, with hot, dry summers. Which biome does this most likely represent?

Accepted Answer

Mediterranean Woodland & Shrubland

Question 11

Which biome has the highest diversity of tree species and is a major source of medicines originally derived from plants?

Accepted Answer

Tropical Rain Forest

Question 12

Human activities have historically been light in which biome, but are now increasing substantially, threatening its ecological integrity?

Accepted Answer

Boreal Forest

Question 13

Which of the following best describes the role of mycorrhizae in tropical rain forest soils?

Accepted Answer

They help plants obtain nutrients from nutrient-poor, acidic soils.

Question 14

A biome is located between 50° and 65°N latitude, has long winters, short summers, and is dominated by coniferous trees. Which biome is this?

Accepted Answer

Boreal Forest

Question 15

Which biome is most likely to experience the formation of 'islands of fertility' under shrubs due to poor drainage or evaporation?

Accepted Answer

Desert

Question 16

Which of the following is a major human impact on Mediterranean woodland and shrubland biomes?

Accepted Answer

Clearing for agriculture and urban development.

Question 17

Which biome is most likely to be found in the rain shadow of a mountain and is characterized by sparse vegetation and low animal abundance?

Accepted Answer

Desert

Question 18

Which of the following best describes the climate and vegetation of temperate grasslands?

Accepted Answer

Moderate precipitation, deep fertile soils, dominated by herbaceous plants.

Question 19

Which biome is most likely to have moderate soil fertility, evergreen trees and shrubs, and a long history of human intrusion?

Accepted Answer

Mediterranean Woodland & Shrubland

Question 20

A region is located within 10° latitude of the equator, has little temperature variation, and receives over 2000 mm of rain annually. What is the most likely dominant vegetation type?

Accepted Answer

Tall, diverse trees forming a dense canopy.
