Click on the flashcard to see the answer



What are the two main types of grasslands?

The two main types are temperate grasslands and tropical grasslands (savannas).

What characterizes the climate of tundra biomes?

Tundras have cold climates with short growing seasons and permafrost soil.

Name a distinctive feature of savanna ecosystems.

Savannas are characterized by a mix of grasses and scattered trees, with seasonal rainfall.

How do animals in the tundra adapt to cold temperatures?

Many have thick fur or feathers and layers of fat for insulation against the cold.

What process prevents trees from thriving in grasslands?

Frequent fires and grazing prevent tree growth and maintain grass dominance.

Which continent is home to the largest area of savannas?

Africa is home to the largest savanna ecosystems.

How does biodiversity in tundras compare to that in grasslands?

Tundras generally have lower biodiversity compared to more fertile grasslands.

What is the primary vegetation in tundra regions?

Mosses, lichens, and low shrubs dominate tundra vegetation.

What happens to the tundra biome during the summer?

The permafrost partially thaws, and a burst of plant and animal activity occurs.

Which animal migrates vast distances in response to seasons in savannas?

The wildebeest is known for its massive seasonal migrations in savannas.

What is the impact of human agriculture on grassland ecosystems?

Agriculture can lead to habitat loss, soil degradation, and reduced biodiversity.

What is the role of fire in maintaining grassland biomes?

Fire helps control woody plant growth, recycles nutrients, and stimulates new growth.

Name a country where the Arctic tundra is found.

The Arctic tundra can be found in countries like Canada and Russia.

What is one challenge faced by tundra ecosystems due to climate change?

Warming temperatures can lead to permafrost thaw and habitat alterations.

What is a common adaptation of grassland plants to withstand drought?

Grassland plants may have deep root systems to access water deep in the soil.
