Q3TYU - Campbell Biology

Question

Which of the following is characteristic of most terrestrial biomes?

(A) a distribution predicted almost entirely by rock and soil patterns

(B) clear boundaries between adjacent biomes

(C) vegetation demonstrating vertical layering

(D) cold winter months

Step-by-Step Solution

Answer

(A) The statement “a distribution predicted almost entirely by rock and soil patterns” is false.

(B) The statement “clear boundaries between adjacent biomes” is false.

(C) The statement “vegetation demonstrating vertical layering” is true.

(D) The statement “cold winter months” is false.

Step 1: Biome

The field of ecology defines a biome as a natural community of plants and animals living in their habitat.

Step 2: Explanation of option ‘(A)’

A rock is a naturally formed substance that comprises grains of minerals and helps learn about earth material and structure.

 

Thus, the distribution must be predicted by weather pattern, latitude, and altitude.

Therefore, the given statement is false.

Step 3: Explanation of option ‘(B)’

Several common elements of the biome are habitat, human activity, plants, and animal adaptations. Various kinds of biomes are grassland, tundra, taiga, temperate forest, and savanna.

 

Thus, nature does not have obvious boundaries. Gradual changes also occur in biomes.

Therefore, the given statement is false.

Step 4: Explanation of option ‘(C)’

The term vegetation represents the life of plants or trees growing in a particular region.

 

Thus, vertical layering is created by trees and bushes in the terrestrial biome (area of land having the same climate and community of plants and animals).

Therefore, the given statement is true.

Step 5: Explanation of option ‘(D)’

In phenology, a season is a weather change due to changes in the earth’s atmospheric conditions during a year.

 

Thus, temperature difference helps determine the plant type growing in a specific region.

Therefore, the given statement is false.
