Terrestrial Biomes: Northern Regions
Multiple Choice
Which of the following best explains why terrestrial biomes are not consistent on every continent across each latitude?
A
Biomes have large overlapping areas called ecotones, making their borders hard to define.
B
Seasonal variation causes biomes to change location.
C
Differences in elevation, soil type, topography & microclimate all contribute to which biome is present.
D
All of the above.
Verified step by step guidance1
Begin by understanding what a biome is: a biome is a large community of plants and animals that occupies a distinct region defined by its climate and vegetation.
Consider the factors that influence the characteristics of a biome. These include elevation, soil type, topography, and microclimate, which can vary significantly across different regions and continents.
Recognize that these factors can lead to variations in biomes even at the same latitude. For example, a mountainous region may have a different biome than a nearby flat area due to differences in elevation and soil type.
Understand the concept of ecotones, which are transition areas between two biomes. These areas can have overlapping characteristics, making the borders between biomes less distinct.
Evaluate the statement that seasonal variation causes biomes to change location. While seasons can affect the characteristics of a biome, they do not typically cause a biome to relocate entirely. Instead, they may influence the temporary conditions within a biome.
