Terrestrial Biomes Flashcard

Front

What is a biome?

Back

A biome is a large geographic biotic unit, a major community of plants and animals with similar life forms and environmental conditions.

Front

What are the main types of terrestrial biomes?

Back

The main types of terrestrial biomes include tundra, taiga (northern coniferous forest), temperate deciduous forest, grassland, savanna, and desert.

Front

What is the role of fire in savanna biomes?

Back

Fire helps to balance tree and grass populations by preventing the overgrowth of trees and promoting the growth of grasses.

Front

What is a key characteristic of grassland biomes?

Back

Grassland biomes are characterized by vast open spaces dominated by grasses, with few trees due to factors like fire and grazing.

Front

What is the dominant plant type in most deserts?

Back

The dominant plant type in most deserts is perennial shrubs, which are adapted to conserve water.

Front

What climate conditions are typical of the tundra biome?

Back

The tundra biome is characterized by long, cold winters and short, cool summers, with low precipitation.

Front

What is the primary vegetation in the northern coniferous forest?

Back

The primary vegetation in the northern coniferous forest consists of needle-leaved trees, such as pines, spruces, and firs.

Front

How does periodic drought affect grassland biomes?

Back

Periodic drought can limit the growth of grasses and influence the types of species that can survive in grassland biomes.

Front

What is the significance of high altitude in grassland biomes?

Back

High altitude is not a major selective force in grassland biomes; instead, factors like fire, grazing, and drought are more influential.

Front

What adaptations do plants in desert biomes have?

Back

Plants in desert biomes have adaptations such as deep roots, thick leaves, and the ability to store water.
